AEGIS = Airborne Early Warning/Ground Environmental Integration Systems

aegis = (Greek) means shield .... or the shield or buckler of Zeus



When I hear of AEGIS, the first thing that comes to my mind is the Ticonderoga-class guided missile frigates of the US Navy.

This legendary ship fascinates every enthusiast with its deadly suite of modern weapons and surveilance systems overshadowed by its benign look.

Aegis Combat System



The Aegis weapons system is a surface-to-air integrated weapons system. It is designed to defend the fleet against any airborne threat. The heart of the Aegis system is the AN/SPY-1 Phased-array radar system coupled with the AN/UYK-1 high-speed computer system. This combination is able to detect incoming missiles or aircraft, sort them by assigning a threat value, assign on-board Standard surface-to-air missiles, and guide the missiles to their targets. Aegis can track up to 100 targets at any given time. The radar panels are flat structures, mounted to give 360 degree coverage around the ship. These are an improvement over the old rotating type of radar in that there are no moving parts. The old rotating radar covered ONLY the area they were scanning. Phased arrays switch rapidly and cover the entire range around the ship in milliseconds.


The Versions (baselines):


Baseline 2 (CG 52-58) consists of the Vertical Launching System, TOMAHAWK Weapon System, and Anti-Submarine Warfare upgrades.


Baseline 3 (CG 59-64) includes the AN/SPY-1B radar and AN/UYQ-21 consoles. Baseline 4 (CG 65-73) integrates the AN/UYK-43/44 computers with superset computer programs developed for the DDG 51.


Baseline 4 is the base Combat System for DDG 51-67.


Baseline 5 was introduced in FY 1992 ships and includes the Joint Tactical Information Distribution System (JTIDS) Command and Control Processor, Tactical Data Information Link 16, Combat Direction Finding, Tactical Data Information Exchange System, AN/SLQ-32(V)3 Active Electronic Counter Countermeasures, and AEGIS Extended Range (ER) Missile. Baseline 5 was developed in three steps (phases):
Phase I integrated AEGIS ER and supports the missile Initial Operational Capability;
Phase II integrated system upgrades including Deceptive Electronic Countermeasures, Track Load Control algorithms, and Track Initiation Processor;
Phase III integrated JTIDS and the OJ-663 color display Tactical Graphics Capability into the AEGIS Combat System.


Baseline 6 will be developed in two phases. Baseline 6 Phase I is planned for the last ship in FY 1994, and Phase III is planned for the first ship in FY 1997. Baseline 6 Phase III is the designation for the computer suite resulting from consolidation of the previous Phase II baseline with variations designed to introduce Tactical Ballistic Missile Defense (TBMD) and Cooperative Engagement Capability (CEC) in in-service ships. Baseline 6 upgrades will include embarked helicopters, Fiber Optics as applied to Data Multiplexing System (DMS), implementation of affordability initiatives, the Radar Set Controller Environmental Simulator (RSCES) and Battle Force Tactical Trainer (BFTT), Advanced Display System, Evolved SEA SPARROW Missile (ESSM), Identification (ID) upgrades Phase I, Advanced TOMAHAWK Weapon Control System (ATWCS) Phase II, Fire Control System upgrades, and the Joint Maritime Command Information System (JMCIS).


Baseline 7 will also be developed in two phases. Baseline 7 Phase I is planned for the last ship in FY 1998 and Phase II is planned for the last ship in FY 2002. Major Baseline 7 upgrades include but are not limited to: AN/SPY-1D(V) radar upgrade, integration of Cooperative Engagement Capability (CEC) and Tactical Ballistic Missile Defense (TBMD) capability (first forward fit implementation), advanced computer architecture, ID upgrades Phase II, Cueing Sensor, STANDARD Missile-2 Block IIIB full integration, Advanced Integrated Electronic Warfare System (AIEWS) Phase I and II, Light Airborne Multipurpose System (LAMPS) helicopter Mark III Block II, Advanced Tactical Support, integrated Naval Surface Fire Support (NSFS), and Mark 50 torpedo with Periscope Depth Attack.

Background:

For more than 40 years, the US Navy has developed systems and tactics to protect itself from air attacks. Since the end of World War II, several generations of anti-ship missiles have emerged as the air threat to the fleet. The first combatant ship sunk by one of these missiles was an Israeli destroyer in October 1967, hit by a Soviet built missile. The threat posed by such weapons was reconfirmed in April 1988 when two Iranian surface combatants fired on US Navy ships and aircraft in the Persian Gulf. The resulting exchange of anti-ship missiles led to the destruction of an Iranian frigate and corvette by US built Harpoon missiles. Modern anti-ship missiles can be launched several hundred miles away. The attacks can be coordinated, combining air, surface and subsurface launches, so that the missiles arrive on target almost simultaneously.

The US Navy's defense against this threat has continued to rely on the winning strategy of defense in depth. Guns were replaced in the late fifties by the first generation of guided missiles in their ships and aircraft. By the late sixties, these missiles continued to perform well, but it was recognized that reaction time, firepower, and operational availability in all environments did not match the threat. To counter this, an operational requirement for an Advanced Surface Missile System (ASMS) was promulgated and a comprehensive engineering development program was initiated to meet that requirement. ASMS was re-named AEGIS (after the mythological shield of Zeus) in December 1969.

The Aegis system was designed as a total weapon system, from detection to kill. The heart of the AEGIS systems is an advanced, automatic detect and track, multi-functional phased-array radar, the AN/SPY-1. This high-powered (four megawatt) radar is able to perform search, track and missile guidance functions simultaneously with a capability of over 100 targets. The first Engineering Development Model (EDM-1) was installed in the test ship, USS NORTON SOUND (AVM 1) in 1973.

AEGIS is currently carried aboard 2 types of ships. The TICONDEROGA-class cruisers were the first. These ships are often fitted with 2 MK 41 VLS. They can carry up to 122 missiles of all types, including Tomahawk, Standard and SLAM. These ships carry a "full" AEGIS System. The second type of ship is the ARLEIGH BURKE-class destroyer. The AEGIS System carried aboard these ships is slightly less capable than the full AEGIS. These ships carry the same complement of missiles as the cruisers.

Currently there are four ship classes in the world equipped with the AEGIS Combat System:

United States:
-The TICONDEROGA-class
-The ARLEIGH BURKE-class

Japan:
-The Kongo-class

Spain:
-The F-100 frigates




The USS Philippine Sea, another ship gifted with such an amazing system.

http://navysite.de/cg/cg58.html

really impressive ship system but it is really capable of shooting down ICBMs that can carry multiple warheads? i think not, its a system designed to defeat air-luanched, ship-launched, land-launched anti ship missiles and cruise missiles but not advanced ICBMS with multitple independently targeted reentry vehicles (MIRV)

Japan's own AEGIS-equipped Kongo-class ships.





DDG Kongo Class
The Kongo Class is the 4th generation Guided Missile Destroyer (DDG) and has a different appearance and contents from previous Japanse DDG designs. The largest size among DDG and SPY-1D AEGIS radars equipped on the four faces of the bridge prove a capacity of this type. This class of four ships is complete, and assigned to 4 escort flotillas as the core ship.

The JMSDF maintains four Escort Flotilla, with each composed of 2-3 air-defense ships, including Kongo class AEGIS ship, and 5-6 anti-submarine destroyers, and 8 ASW helicopters, or as it is more commonly known, the 88 Formation. Japan has four of them, named 1st through 4th Escort Flottilla. Although the information processing ability and flagship ability of the Aegis warship is superior, the flagship of the Escort Flotilla is the DDH.

Japan was the first state (outside the United States) to acquire the superlative Aegis fleet defence system, fitted in the Kongo-class destroyers. The Aegis system's maximum detection distance, the number of simultaneously tracked targets, reaction time and missile range is superior in all points by comparison with the former Tartar system. The ASROC anti-submarine rocket, which is the anti-submarine weapon, along with the Standard anti-aircraft missile, are launched from the VLS (the vertical launch system) which is imbedded in the front and back section decks. The third unit of the class [Myoko] was the first with SM2MR Block III (the Block II was used on the first two ships). They are to receive New ASROC (presumedly ASROC with Japanese lightweight torpedo), and to be fitted with P/S(1)2 12.7mm or 20mm with night vision equipment.

The Kongo is an improved version of the U.S. Navy’s Arleigh Burke class, displacing 9,485 tons (full load). It is a substantial departure for Japan in terms of size and capability in its surface fleet. There also are qualitative differences between Japan’s modern ships with their well-trained crews and the older, less capable ships of other East and Southeast Asian navies.

That's a concern alright.

ICBMs usually fly high above the clouds which may make it hard for the AEGIS-equipped ships to intercept it. The missile will only descend or worse, set the next stage, which is launching multiple rockets from it's main body, when the missile is nearing its target. Just my analysis though, based on my limited knowledge on the system.

Nonetheless, NoKor is just near Japan. Probably the missiles coming from NoKor will be fired in the region nearest to Japan to lessen Japan's reaction time once the missile's flight is detected by Japan's radars.

With that, the missiles will be flying low considering the distance between NoKor and Japan.

With this scenario, the AEGIS and it's SM2 or better models, will be able to track and intercept the missile.

The only concern is that when the ICBM flies beyond the reach of the SM2 missiles while closing the gap.

Nonetheless, land-based missiles like the Patriots, may take over the task from the AEGIS ships of intercepting the missiles when the missiles get past the range of th ships.

I am not sure if the SM2 missile cant intercept ICBMs high above the clouds though.

Good thing is that an SM3 model, a similar platform that is being developed to handle ICBM threats are now in the pipeline.

Lookee here.....


RIM-161 SM-3 (AEGIS Ballistic Missile Defense)

Standard Missile-3 (SM-3) is being developed as part of the US Navy’s sea-based ballistic missile defense system and will provide theater-wide defense against medium and long range ballistic missiles. In 1992, the Terrier LEAP (Lightweight Exo-Atmospheric Projectile) demonstration program culminated in four flight tests and demonstrated the feasibility of theater-wide ballistic missile defense. This program evolved into today’s SM-3 development program which is based on the SM-2 Block IV airframe and propulsion stack, but incorporates a Third Stage Rocket Motor, a GPS/INS Guidance Section and the SM-3 Kinetic Warhead.

The United States Navy and the Missile Defense Agency are developing Standard Missile-3 (SM-3) as part of the Aegis Ballistic Missile Defense System that will provide allied forces and U.S. protection from short to intermediate range ballistic missiles. The SM-3 Kinetic Warhead (KW) is designed to intercept an incoming ballistic missile outside the earth’s atmosphere. SM-3 is under development by Raytheon at its Missile Systems business unit in Tucson, Arizona.

.................

Raytheon's next hit-to-kill success with the sea-based STANDARD Missile-3 occurred on 11 December 2003. Between January 2002 and late 2004, the Aegis BMD system had successfully intercepted targets in space four times with SM-3. In all the flight tests, the SM-3 was launched from a US Navy cruiser under increasingly realistic, operational conditions.

On 24 February 2005 the Aegis Ballistic Missile Defense (BMD) Weapon System and Standard Missile-3 (SM-3) destroyed a ballistic missile outside the earth's atmosphere during an Aegis BMD Program flight test over the Pacific Ocean. The Feb. 24 mission -- the fifth successful intercept for SM-3 -- was the first firing of the Aegis BMD "Emergency Deployment" capability using operational versions of the SM-3 Block I missile and Aegis BMD Weapon System. This was also the first test to exercise SM-3's third stage rocket motor (TSRM) single-pulse mode. The TSRM has two pulses, which can be ignited independently, providing expansion of the ballistic missile engagement battlespace. The SM-3 was launched from the Aegis BMD cruiser USS Lake Erie (CG 70) and hit a target missile that had been launched from the U.S. Navy's Pacific Missile Range Facility on Kauai, Hawaii.

yep should get at least 6 of those ticonderoga.....

Spidy,


Singapore seems to have such ships. Could you tell us about this?

How much does it cost? Does your country sell ships like such?

Singapore dun have Aegis type warship for the reason of not trying to incite a armed race and there is no actual purpose for it. Having one of it will definitely be deemed as a aggressive move. But we do have a smaller and more diluted version of the la fayette frigate, the formidable class. True La fayettes are 130m while singapore type is onli 114m. Singapore Technologies(marine) seems to have mastered the skill of stealth as ST websites seems to advertise this 81m OPV or corvettes. :specool: :rifle:

This is the Formidable class frigate of Republic of Singapore:

pretty 'formidable' ! specially the aster air-to-air missiles,apparently singapore is the only foreign market where france sold it!(i think,please correct me if im wrong here) wonder how much they paid for it.
the Herakles multi-function radar seems top notch but i havent read anything else about this radar other than tihs formidable application.

but! im pretty sure its nothing compared to this two:

for both of them share the same eyes.
The Thales Nederland SMART-L long-range air and surface surveillance and target indication radar, and Thales Nederland APAR Active Phased Array Radar.
and its a later design so better integration/automation,the american ship ticonderoga i think needs 350 crew to run!but the U.S.Navy is losing crew to attrition(end/none-renewal of crews contract to civil life).
The american AEGIS AN/SPY-1 is about unveil an upgraded version(i think ver F na ata but please correct me if im wrong).
also the SMART-L is about to introduce an upgrade.so that should assure thier investment :thumb: .
but theres a lot of life yet for the AEGIS for there a few foreign projects for it.

also to add to fizzy123, i think they already did!(start a small ASEAN naval arms race)or at least they fueled the fire when they announce the acquisition of the Formidable class.everybody seems to have the itch suddenly to buy ships.like the malaysia buying 6 Meko A100 corvettes with the option to buy 20 more!!!
heres what they look like: (yes they are already built by now,i swiped the pic from some Malaysian forum they said this is taken somewhere in langkawi if i remember it right.)

its a nice boat kung hindi lang grossly over priced($165m reported :wow: ) i would love for us to have it.
heh even us have the itch to buy.

comrade el ramon: the French sold the navalized Aster 15 surface-to-air missiles to the Saudis. the Royal Saudi Naval Forces purchased three Al Riyadh (modified La Fayette) class guided-missile frigates from French shipbuilder DCN some years ago.

Navy Theater Wide, AEGIS and Sea-based Global Missile Defense

Platforms

Two ship classes in the United States Navy currently field the AEGIS radar and weapons package- Ticonderoga-class guided missile cruisers and Arliegh Burke-class guided missile destroyers. Additionally, the Japanese Kongo-class destroyers and Spanish F-100 frigates also house the AEGIS system. Cooperation with allies will be an integral part of sea-based global missile defense as our ships will have to cruise far from home in the littoral waters surrounding possible hostile states armed with ballisitic missiles to enable boost phase intercepts.

Missiles: The Standard Missile

The Standard Missile is the Navy’s prime fleet-area air defense weapon and was developed to replace first generation Talos, Tartar and Terrier air defense missiles. It is a solid propellant-fueled, tail-controlled, surface to air missile fired by surface ships. The SM homes in on high-altitude anti-ship missiles during its terminal phase of flight by utilizing the Aegis Radar system and mid-course guidance with radar illumination of the target by the ship. The Standard Missile family plays a paramount role in the theater ballistic missile defense. There are several versions of the Standard Missile:

Developed in 1967 as the first generation Standard Missile, the SM-1 served as the primary missile of the U.S. Navy and several other navies. It is a home-all-the-way missile in medium and extended range versions designed for anti-air, anti-missile, and anti-ship warfare.

The latest generation of Standard Missile, SM-2, utilizes an imaging infrared seeker in terminal phase of flight. It maximizes advanced signal processing, communication techniques, and propulsion improvements to provide substantial increases in intercept range, high and low altitude intercept capability, and performance against advanced threats. The SM-2 employs a vertical launch system, Command Midcourse Guidance, an ECM resistant monopulse receiver for semi-active radar terminal guidance, and a blast fragmentation warhead. The SM-2 provides medium range defense for Ticondergoa-class AEGIS cruisers, Arleigh Burke-class AEGIS destroyers, California and Virginia-class nuclear cruisers and some Kidd-class destroyers.

In order to meet the NTW and the Sea-Based Global Missile Defense roles, the Standard Missile will have to be modified. One such modification, increasing the speed of the missile, will be easily achieved as the current deployed version of the Standard has been intentionally slowed-down so that it does not risk violating the restrictions of the ABM treaty. See this PDF file to see modifications that will have to be made to upgrade the Standard.


--------------------------------------------------------------------------------

Radars and Sensors

SPY-1D Phased Array Radar


The backbone of the AEGIS Weapons System is the SPY-1D phased array radar. SPY-1D is the most technologically advanced radar in the world, able to track marble-sized targets in excess of 100 miles. All the targets tracked by the SPY radar are monitored by the ship's Command and Decision system. If a target is determined to be a threat, the ship's crew can issue orders through the Weapons Control System, and engage the target with missiles, guns, and/or CIWS.Significant funding is being allocated by the US Navy to upgrade or modify existing SPY-1D Aegis systems aboard the US Navy's CG-47 guided missile cruisers and DDG-51 destroyers to accomplish the TBMD function to meet US Navy requirements. These upgrades to the Aegis system consist of improved or new missiles, improved and new radars, and significant modifications to the software. SPY-1D is the only radar being considered by the US Navy today for upgrade to accommodate a TBMD capability.

Sensors

The primary sensor for naval TBMD active defense will be the Aegis SPY radar. Its TBM-tracking capabilities are being explored and expanded through the use of new computer software that will produce a TBMD-capable Aegis system. Thus altered, SPY radars have "demonstrated the ability to track TBMs at ranges well in excess of 500km."

Report to US Congress on Theater Missile Defense Architecture Options for the Asia-Pacific Region

http://72.14.235.104/search?q=cache:Ri8r7Y...ph&ct=clnk&cd=6

i just came across this thought while reading this thread...

would it really be necessary for the PN to buy Aegis-equipped warships (the AFCON corvette included)?

for me, a simple guided-missile corvette equipped with eight MM40 Exocet anti-ship missiles, two four-cell Tetral launchers for Mistral air defense missiles, one 76 mm OTO Melara main gun, two 20 mm cannons and six 12.75 inch tubes for anti-submarine torpedoes would be "initimidating enough" to potential adversaries since such ships, although modestly-armed, still have the necessary firepower to cause significant damage.

if the rationale for buying Aegis-equipped warships is to protect the Philippines from the onslaught of ballistic missiles such as Scuds and Taepodongs, i guess we would just have to invest on land-based air defense batteries such as the Patriot air defense system and the S-300PMU1/S-300V air defense system instead of getting overly expensive Aegis-equipped warships. :dunno:

Good point in there, Israeli.

Actually, my motive was to emphasize the capability of the AEGIS system first. When we are through with it or when we are satisfied enough about what this is all about, then we may move on to the next aspect, which is finding out the best setup for our cash-strapped govt.

My idea, since the AFP is programmed to buy OPVs and other ships later, is to add the possibility of buying ships that may not be exactly as powerful as the new AEGIS-equipped ships of the US and Japan or better yet, find an OPV with which a system similar to AEGIS is already integrated into.

And yes, we can analyze now how many land-based SAMs and ship-based SAMs should we set in place.

ehe since this is a AEGIS thread,maybe this..

Venezuela is getting 4 new corvettes based on SPY-1K

kinda funny with the Bush/Hugo Chavez spat but their getting the SPY-1 radar hehe

^ that will not be possible. with the Americans already barring the sale of SPY-1Ks to the Venezuelans, the Spaniards are already selling "modified" AFCON corvettes to their former colony in South America.

Comrades, what is the best Phased Aray System ?

1. AEGIS- used by US/JAPAN/SPAIN

2. EMPAR-used by FRANCE/ITALY

3. APAR- used by DUTCH/GERMAN

4. SAMPSON- used by UK

AEGIS i think...

^ We better discuss here the radar's and its system here. Since we already touch AEGIS specially SPY-1 radar. why dont we include other ship based multi-function radars such as:

[/QUOTE]
1. AEGIS(AN/SPY-1D and its variant) - used by US/JAPAN/SPAIN

2. EMPAR - used by FRANCE/ITALY

3. APAR - used by DUTCH/GERMAN

4. SAMPSON - used by UK
[QUOTE]

the reason why i would like to push thru this very specific radar system is to gain better understanding onboard ship or ship based radar system.This will benefit us and will be usefull for the future of the Philippine Navy.

We can give more scrutiny and atleast on what kind or specific radar system for ships and its alternative. The most reasonable purchased for 3rd world countrys(like Philippines) in case we would like to obtain this units. the implications of US government restriction of getting the SPY-1D radar system for the 3rd world country is very obvious. This is why i brought the other ship based radar system to be discussed since we touch it already.

Im hoping that we can disect one system at a time to become fruitfull in our search for better radar system.

Ask ko lang, any new updates on how they reload these while on a mission? Most of those that I encountered about it is that it takes time to reload and forget it if its rough seas condition.

APAR(Active Phased Array Radar)
User: Netherlands, Germany, Canada




APAR Shines Again in Live Firing Tests
26 April 2005 11:04

Once again, the Thales Anti Air Warfare suite proved its status as most advanced naval defence system in the world.

During live missile firing tests held by the Royal Netherlands Navy (RNLN) in March 2005, the APAR radar system successfully guided two Evolved SeaSparrow Missiles (ESSM) and two Standard Missiles (SM2) simultaneously to various targets, destroying them all.

In March of this year the RNLN performed three test scenarios on board of “De Zeven Provinciën”, the first of class of the new Air Defence and Command frigates, in the vicinity of the island of Madeira. The tests constituted an absolute first in any test firing: APAR engaged two drones by guiding four missiles simultaneously to the targets, using only one of its four faces. And thanks to the system's short reaction time and high accuracy, this face did not nearly reach its maximum capacity, leaving plenty of room for even more engagements. Based on Interrupted Continuous Wave Illumination (ICWI), the system’s performance in these tests unambiguously proves APAR's capability to protect fleets and other objects at open sea, or in a littoral environment, against a multitude of air threats. APAR's performance in these tests constitutes a milestone in naval defence. No other ship in the world has ever shown this kind of engagement capability.

Previous tests with ICWI guidance technique
The first missile tests of APAR were held in November 2003, also on board of “De Zeven Provinciën”. In August 2004, the Air Defence and Command Frigate "Sachsen", the first of class of the German Navy F124 frigates, successfully tested the system as well. These tests consisted of firing 21 SM-2 and ESSM missiles against several types of threats. They unequivocally demonstrated the system's capability against multiple targets.

APAR
APAR, Thales' Active Phased Array Radar, is the world's most sophisticated multi-function radar. Its non-rotating antenna houses four faces that together cover the full 360 degrees. Each face consists of more than 3000 very small radar transmitter/receiver (T/R) elements, giving the radar its unique capabilities and high operational availability. The inherent agility of APAR guarantees a high performance in the most adverse conditions, under severe electronic protection measures. APAR makes use of Interrupted Continuous Wave Illuminations (ICWI) technology, a concept that has been developed in the international Tri-lateral Frigate Cooperation formed by the Netherlands, Germany and Canada. This technology enables APAR to simultaneously guide multiple missiles to one or more threats. The ICWI technology has recently been contracted to the Japanese Maritime Self-Defence Force.

About Thales
Thales is an international electronics and systems group serving defence, aerospace, security and services markets. The Group employs 60,000 people worldwide and generated revenues of 10.3 billion euros in 2004.

An important task of APAR is to detect flying objects. Detected objects are taken in track by APAR. The Command and Control System of an ADCF has to identify detected objects. Objects that are identified as being hostile are called targets and are possibly engaged by the ADCF. In case of an engagement, the Advanced Weapon Control System chooses the weapon system and salvo size and determines the engagement moment. In case of an engagement by missiles, APAR has to guide the missiles to the target and has to verify whether the intercept has been successful or not.

Objectives
The objectives of this study are to develop and evaluate algorithms for the scheduling of the tasks an APAR and for the determination of engagement moments of defensive missiles.

Detailed problem description Scheduling
APAR consists of four faces, each covering a sector of approximately 100 degrees. A face is practically independent of the other three faces.
A face of APAR has to execute several tasks. Three types of tasks have to be executed continuously:
target track to keep targets in track,
horizon search to detect undetected objects and
low priority track to keep e.g. friendly aircraft in track.
Furthermore, a number of tasks have to be executed during each engagement of a missile against a target. The most important tasks are

missile track,
midcourse guidance (to guide the missile to the target during the first part of the engagement),
terminal illumination (to guide the missile to the target during the final part of the engagement), and
kill assessment (to verify whether the engagement has been successful or not).
It is possible that APAR can not completely execute the search task during busy periods. In such cases, APAR can process information on objects supplied by other detection systems, called cueing. In this way, APAR can track objects that were not detected by APAR itself.

Each task consists of a series of dwells that have to be transmitted (a dwell train). The length of a dwell, called the dwell time, and the desired time between the begin of transmission of two consecutive dwells, called the update time interval, are given per task.
The scheduling problem for one face of APAR is, given the periods during which the tasks have to be executed, to determine the transmission moments of the dwells so that dwells are not transmitted simultaneously. Simultaneous transmission of dwells is, apart from some exceptions, impossible. It is possible that each schedule that meets this requirement cannot transmit all dwells, or cannot satisfy all desired update time intervals. In such cases, the deviations from the desired dwell patterns have to be as small as possible.

Engagement moments
Engagement moments form input for the scheduler of APAR. The influence of the engagement moments on the quality of the schedule can be substantial. In the determination of the engagement moments, one has to take into account that loads should not be too large and that overlaps between periods during which incompatible tasks have to be executed, are not too large. Also other aspects are important in the determination of the engagement moments, e.g. the kill probability of a missile, which depends on the range at which intercept takes place.
Insights obtained with the model SEAPAR will be used in the high-level model SEAROADS (Simulation, Evaluation, Analysis and Research On Air Defence Systems). This model can analyse the all-in performance of maritime air defence systems, including hard kill and soft kill systems. SEAROADS can be used at single ship level, it also enables the study of co-operative air defence of a task group.

AEGIS daw... (basahin nyo na lang)

China's AEGIS Class

sana i-post nila sa internet (P2P) yung file..hehe joke lang.

jammerjamesky,

like what i said on the previous page,for me the most potent radar around is oviously APAR multi-funtion radar/ SMART-L sulveilance radar combination.

there are two kinds of "phased array radar":
1.passive phased array radar (PPAR)
2.active phased array radar (APAR)

the AEGIS system uses the SPY-1 radar developed in the 1970's uses the PPAR set-up.
for at the time active phased array T-R module's price is too expensive,
making a radar out of it is out of the question.
the AEGIS system's greatest strength is the systems maturity.
but it's not perfect.(il just quote fas.org)

STRENGTHS
*ANSPY-1 multifunction, phased array, fire control quality radar.
*Very rapid transition from SPY-1 silent to full radiate and full situational awareness.
*Fast reaction, fully/semiautomatic combat systems. Initial detection to first missile movement in less than 10 sec.
*Salvo rate of less than 2 sec per launcher (CG-52 and above with MK 41 VLS)
Mix of multiple SMs.
*Max field of fire and min blockage zones
*Must illuminate target only for a short duration prior to intercept.
*AN/SPY-1 radar variable sensitivity feature allowing radar sensitivity to be tailored to threat RCS, environment, and tactical situation.
*Weapons & ID doctrine capable of automatic and semiautomatic response/action.
*Doctrine software assists w/ ID

WEAKNESSES
*The system is designed for blue water and littoral operations however AN/SPY-1 configuration must be modified to look above the terrain to avoid causing excessive false targets from land clutter. These configuration changes may increase ship susceptibility to low and fast targets.
*Once a target is engaged and the initial salvo fired, WCS will not allow the target to be reengaged (second salvo) until a kill evaluation has been completed.
*AN/SPY-1 antenna height is lower than the AN/SPS-49 radar system resulting in reduced radar horizon.
*DDG-51 Class are not equipped with a AN/SPS-49 radar (no secondary air search radar)
*Must hold an AN/SPY-1 track. Cannot engage on a remote or AN/SPS-49 track unless equipped with CEC.

it's greatest claim to fame for me is when it mistook an Iranian Airbus A310 civilian airliner fulll of passengers as a attacking fighter and shot it down resulting in 290 civilian fatalities.

nowadays the APAR technologies are maturing.and they are peeking in function!
(hence unproven)

now we get to see Thales APAR,MRR,etc..
we are talking about APAR naval radars here but it is basically the same as aviation's AESA radar as T-R modules are maturing like Northrop Grumman AN/APG-80 of the F-16 block 60.

APAR is basically microchip modules (T-R modules) combined together to make the radar face.
so there's no central transmiter/wave guide like in the old radars.
each module can make it's beam swing left-to-right,up-down.
as you've already posted above the virtues / features of Thales APAR.
it is also both PPAR/APAR have a longer lifespan
apar tends to decay gracefully..when one t-r module dies,theres still thousands operating!
can scan and change scan mode at the speed-of-light..since theres no mechanical gimbal to point the beam and scan pattern to satisty a particullar scan mode.

and more,kayo na magtuloy.

1. AEGIS(AN/SPY-1D and its variant) - used by US/JAPAN/SPAIN

2. EMPAR - used by FRANCE/ITALY

3. APAR - used by DUTCH/GERMAN

4. SAMPSON - used by UK

Im just curious who among those radar listed that can perform and destroy more detected targets whether short or long range in Simultaneous engagement??

cheers :armycheers: Peace to all.

i really do not think we need Aegis-equipped warships. i believe that a multi-purpose corvette equipped with either vertical launched ESSM or Barak or short-range SAMs such as Mistral or RAM would work well with the Philippine Navy. in fact, i have always adhered to the idea of the PN having a fleet of multi-purpose corvettes equipped with eight MM40 Exocet SSMs, two four-cell Tetral SAM launchers for Mistral missiles, one OTO Melara 76 mm Super Rapido main gun, two MSI Defense 25 mm guns and six 12.75 tubes for ASW torpedoes for its surface combatant force.

if our only concern for having Aegis-equipped warships is due to the threat being posed by ballistic missiles, then perhaps such concern can be addressed by acquiring land-based SAM systems such as the Patriot and the S-300PMU2.

i think this is the fair comparison of the APAR radar..
AN/SPY-3 Multi-Function Radar
both do search,illumination function in one,
both X-band (as i remember apar does but correct me if im wrong)
but limited info available for SPY-3MFR.

good point.

that's fitting for our short to medium term plan, if there is such.

but since our purchases will only come around 10 years later, then it's still practical to get several AEGIS-equipped ships for our fleet.

land-based missile interceptors will be essential.

Pretty shocking. The link below is to an interactive screen that shows the defects of the USS Stout and USS Chosin. I'm surprised that this story, which is nearly two weeks old, has not been posted here yet.

A fitting name then.
