Arleigh Burke class Destroyer |
BACKGROUND
As the US Navy's newest class of destroyers, Arleigh Burke class Guided Missile Destroyers are considered to be their most survivable surface combatant. The Arleigh Burke class has an all steel hull with extensive armor and kevlar plating covering sensitive areas of the ship. The Arleigh Burk was also the first ship to use shaping techniques to reduce the radar signature of the hull which reduces thier detectablity.
The Arleigh Burke class is assigned to high threat areas and strike opperations as it is designed to defend against enemy aircraft, missiles and submarines. The AEGIS air defense system, a 90 cell Vertiacal Launching System, Harpoon anti-ship cruise missiles, and other weapons allow the ship to handle it's assigned rolls well.
Construction of the Arleigh Burke class started in 1985. Flight I was replaced by Flight II in 1992 which featured improvement to the radar, missile, electronic countermeasures, and communications systems. The older Flight I ships will be gradually upgraded to Flight IIs. Flight IIA, which was introduced in 1994, added a helicopter hanger and two helicopters. Previous ships only had a large hanger deck. By 2008 a total of 57 Arleigh Burke class ships will have been constructed.

NOTES:
- Depleting the MDC of the main body will put the destroyer out of commission. All internal systems will shut down, the ship itself will be an unsalvageable sinking wreck.
- 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.
- Destroying the flight deck will greatly impair the destroyers ability to deploy and recover Helicopter.
- 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.

8. 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: CConfuses 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.
9. MK 36 SUPER RAPID-BLOOMING OFF BOARD CHAFF/ FLARE DECOY DISPENSORS (4):
The destroyer's counter-measures dispensors consist of four 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.
01-50 Missile/s detonated by Chaff/Flare
51-75 Missile/s loses track of target and veers away in wrong direction, (may lock onto another target)
76-00 No effect, missile is still on target
- Payload: Three of each type (per launcher). Reloads are automatic with 3 reloads per launcher before a manual reload is required. Stores hold 10 full reloads of the system.
SYSTEMS OF NOTE:
- LIFE SUPPORT SYSTEMS: The destroyers have sufficient food, water, fuel and amenities to support up to 350 people for up to 6 months. In an emergency the cruiser can support up to 800 people at one time, though living conditions onboard will get extremely cramped at that point.
- LONG-RANGE LASER/SATELLITE RELAY COMMUNICATIONS: The impressive communications array of the destroyer can communicate with up to 500 craft simultaneously at ranges of up to 1,440 km. This range can be boosted indefinitely by using satellites or other spacecraft as to relay communications.
- LONG-RANGE RADAR: The radar array of the destroyer is equally as impressive as the communication system, and can track and identify up to 500 craft simultaneously. The radar system has a 3,200 km range.
- ENGINES: The Destroyer features four engines, consisting of 4 General Electric LM-2500 Gas Turbine Engines (80,000 shaft horsepower)
- DECOYS: Sea Gnat (Outfit DLB) decoys, SLQ 39 chaff buoy, SLQ 95 AEB and a SLQ-25A Nixie towed torpedo decoy. The Sea Gnats are mounted on Hunting Engineering 130 mm six-barrel launchers for Anti-Torpedo defence.
