The EAW-22 Ship launched land attack cruise missile started life as the Interim Ship Launched Attack Missile (ISLAM) designed to provide the Navy with a quickly available land attack capability that could be fired from existing Yakhont anti-ship missile launchers fitted in nearly all Elias Navy warships.
The design originated with plans to mate the guidance system of the EAW-12 Air Launched Cruise Missile (http://www.nationstates.net/forum/viewtopic.php?t=56000) with the Yakhont-3 (Klamath/Tarasovka) missile system which could then be used similarly to a Tomahawk and attack an array of ground based targets from many miles away. The end result was a system that was far more suitable for the role than originally planned as the airframe was changed considerably. In tests the EAW-22 has proven to be more lethal, as accurate as and less vulnerable than the TLAM.
The EAW-22 is a stealthy cruise missile of around 3600 kg carrying a powerful conventional warhead. It is a ship/submatine launched, conventionally-armed, long-range, stand-off, precision weapon, which is deployable at night or day, in nearly all weather and operational conditions. It is able to destroy sensitive and highly protected targets (command bunkers, communications centers, etc.) with very great accuracy, and has a range of over 850 nautical miles after an entirely autonomous terrain-following flight at very low altitude. It was developed to attack and destroy a wide spectrum of static, high value, heavily defended targets and the warhead is optimised for use against hardened targets.
Flight profile & Guidance
The first phase of the mission planning regime ensures that the missile navigates to the target with maximum survivability and then enters a robust target acquisition and terminal guidance phase. For complex and pre-determined missions, much of this data would have been pre-prepared earlier at the Command Headquarters.
From launch, the missile maintains a very low cruising altitude. Its inertial navigation is continuously updated through information supplied by its navigation system following the ground by digital terrain profile matching and by GPS (Global Positioning System). This redundancy provides it with excellent navigational precision and resistance to countermeasures.
On approaching the terminal phase, the missile will initiate a bunt maneuver, pre-selected during mission planning, to obtain the best combination of acquisition probability and lethality against the target. As the missile climbs, it will jettison its nose cover, thereby enabling the missile high resolution imaging infra-red sensor to view the target area ahead.
The missile’s image processor will compare the actual image features with a reference set of features, determined during mission planning. When a feature match is achieved the target will be acquired and the required aim point selection tracked and used as the reference for the missile terminal guidance. As the missile closes in on the target the acquisition process will be repeated with a higher resolution data set to refine the aim point. Tracking will continue against this refined aim point until the precise target location is identified.
When engaging hard targets, such as Hardened Aircraft Shelters or bunkers, the missile will strike the target at the estimated optimum dive angle, selected during mission planning. On impact the detonation sequence commences. The precursor charge will perforate the target structure, and any soil covering, and the follow through penetrator warhead will continue to penetrate inside the target to be detonated after a pre-selectable fuse delay.
Should the mission be against a target with potential high collateral damage, the mission will be aborted if the target identification and acquisition process is unsuccessful. In this case the missile will fly to a predetermined crash site.
Warhead
Pentrating Warhead
The BROACH multi-warhead system, achieves its results by combining an initial penetrator warhead with a secondary follow-through bomb, supported by multi-event hard target fuzing. The outcome is a warhead and fuze combination that provides for the defeat of hardened targets more than twice that achievable for equivalent single penetrating warhead types, at an equivalent weight and velocity. The warhead technology can be scaled and configured for a variety of weapon payload and targets requirements.
Anti-personnel/Anti-Armour
Altenratively the M51 Missile Warhead can be used against personnel and armoured targets normally dispersed over an area of 150-200 yards. Each missile dispenses a cargo of approximately 850 antipersonnel and antimateriel M74 bomblets.
The warhead is based around the M74 bomblet:
The M74 bomblet is very similar to the M85 bomblet used in UE's
Advanced Artillery submuntions (http://www.nationstates.net/forum/viewtopic.php?t=74839) but slightly larger.
The valuable and unique Self-Destruct Dual Purpose (Anti Personnel & Anti Armor) M85 Bomblet ensures that no hazardous duds are encountered by advancing friendly forces. A unique self-destruct mechanism detonates those bomblets that did not explode by impact and another backup mechanism prevents inadvertent arming of duds by manual means. No stored energy is contained in the bomblet fusing system, thus complying with the most severe military standards.
The bomblet utilises a small HEAT (high Explosive anti-tank) warhead
and yields about 1500 fragments dispersed over a large lethal area. The shape-charge penetrates more than 120mm of RHA steel and is ideal for attacking armour and personnel alike.
