Tarawa class Amphibious Assault Ship

BACKGROUND

Primarily designed to land and sustain US Marines during any shore hostility, this ship can bring a bunch of Marines to almost any coast in the world. It is designed to operate independently or as a unit of a force as a flagship if need be. It's full length deck can accomidate the AV-8 harrier as well as the OV-10 Bronco. The large well deck in the stern can launch a number of amphibious assault craft either hovercraft or convential. Fitted with an extensive command and control suite this ship gives a task force commander nearly unlimited versatility in directing a mission.

NOTES:

(1) Depleting the MDC of the main body will put the ship out of commission. All internal systems will shut down, the ship itself will be an unsalvageable sinking wreck.
(2) Destroying the command tower will instantly kill the command staff and deprive the ship of all forms of long range communications, radar and targeting. Destroying the main sensory array behind the command tower will have the same effect, but the command staff will not be killed instantly.
(3) Destroying the flight deck will greatly impair the carriers ability to deploy and recover aircraft.
(4) Depleting the MDC of the propellors will leave the ship adrift until such time as they are repaired or the ship is towed back to port.

5. AN/SLQ-32 (V) 3 ELECTRONIC WARFARE SUITE:

Used to defeat hostile radar and Sonar, the ECM/ESM, (Electronic Counter Measures,) jammers will confuse all radar and sonar so that the ships is much harder to be detected or locked onto with radar/sonar guided weapons. This does not give away the position of the ship but it does let the enemy know that they are there. The only way that it can be defeated is with ECCM, (Electronic Counter-Counter Measures).

PRIMARY PURPOSE: Block Enemy Radar/Sonar
RANGE: 50 km
RULES: Confuses all radar/sonar within 50 km, but can be defeated by ECCM, if the ECCM operator gets a higher Sensory Instruments percentage roll against the ECM operator.

MK 36 SUPER RAPID-BLOOMING OFF BOARD CHAFF/ FLARE DECOY DISPENSORS (6):

The carriers counter-measures dispensors consist of six six-barrelled 130 mm Chaff/Flare launchers. Triggered by the Principal Weapons Officer, (PWO,) they will release either a chaff cloud or single flare depending on what the PWO chooses. They are used to confuse enemy missiles attacking the ship. Smart missiles get a 20% bonus when rolling on the below chart.
