RPG STATS

MDC BY LOCATION:

(1) Main Body                                    3795
(2) Command Tower                                 900
(2) Sensor Array (behind command tower)           200
    Hanger                                        800
(3) Flight Deck                                  1000
    Aircraft Elevators	(2)                       400 each
(4) Propellors (2)                                300 each

    MK 49 RAM (2)                                 125 each
    MK 15 MOD 2 Vulcan CIWS (3)                   150 each   
    MK 29 Sea Sparrow (2)                         190 each

    Outer Hull (per 40ft area)                    100
    Interior walls (per 20ft)                      10

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.

WEAPON SYSTEMS:

1. MK-49 RIM-116 RAM ANTI-AIRCRAFT MISSILE LAUNCHER (2): Point defence missile system designed to destroy anti-ship missiles.
   • PRIMARY PURPOSE: Anti-Missile
   • SECONDARY PURPOSE: Anti-Aircraft
   • RANGE: 11 miles (16.5 Km)
   • SPEED: Mach 2+
   • DAMAGE: 2D4x10 M.D.
   • RATE OF FIRE: 1-4 per turn.
   • BLAST RADIUS: 50 feet
   • PAYLOAD: 21 per launcher

2. MK 15 BLOCK 1 20MM VULCAN PHALANX (CIWS) (3): A important Close in defensive weapon of the ship are the primary defence against inner range aircraft and missiles. These guns are almost totally automated and are very effective against low flying aircraft/missiles. These are mounted at various corners of ship and near command tower.
   • PRIMARY PURPOSE: Anti-Missile
   • SECONDARY PURPOSE: Anti-Aircraft
   • RANGE: 1 mile
   • DAMAGE: 5D6 MD per 60 rd burst, and 1D6 x10 for 100rd burst
   • RATE OF FIRE: 5 bursts per round
   • PAYLOAD: 1550 rounds
   • BONUSES: +4 to strike

3. M2HB 12.7MM MACHINE GUN (8): Several of these are mounted during wartime. One on port and one on starboard and one at the bow for detonating mines.
   • PRIMARY PURPOSE: Anti-Aircraft
   • SECONDARY PURPOSE: Anti-ship/Mine
   • RANGE: 2000ft
   • DAMAGE: 1D6 (10 RDS.), 2D6 (20 RDS.), 4D6 (40 RDS.)
   • RATE OF FIRE: 40 Rounds per melee
   • PAYLOAD: 200 rd belts

4. MK29 RIM-7P ESSM SEA SPARROW ANTI-AIRCRAFT MISSILE LAUNCHER (2): Two of these systems defend ship from missile and aircraft threats.
   • PRIMARY PURPOSE: Anti-Aircraft
   • SECONDARY PURPOSE: Anti-Missile/Anti-surface
   • RANGE: 8 nm/8 nm against Surface targets
   • SPEED: 2,660 mph
   • DAMAGE: 2D6x10 M.D.
   • RATE OF FIRE: 1-3 per turn.
   • BLAST RADIUS: 50 feet
   • PAYLOAD: 8 per launcher,

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: 30 miles
   • RULES: Confuses all radar/sonar within 30 miles, but can be defeated by ECCM, if the ECCM operator gets a higher Sensory Instruments percentage roll against the ECM operator.

6. MK 36 SUPER RAPID-BLOOMING OFF BOARD CHAFF/ FLARE DECOY DISPENSORS (4): The carriers counter-measures dispensors consist of six six-barrelled 130mm 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.

STANDARD EQUIPMENT FOR THE WASP CLASS ASSAULT SHIP:

• LIFE SUPPORT SYSTEMS: These ships have sufficient Food, water, fuel and amenities to support up to 5000 people for up to 6 months. In an emergency the ship can support up to 8000 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 ship can communicate with up to 500 craft simultaneously at ranges of up to 900 miles (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 ship is equally as impressive as the communication system, and can track and identify up to 500 craft simultaneously. The radar system has a 2,000 mile/3,200 km range.
• DECOYS: SLQ-25A Nixie towed torpedo decoy, and SLQ-49 floating radar decoy.
• FLIGHT DECK: 9 spots for launching aircraft, parking for 12 helicopters or 6 aircraft.
• LIFTS: There are two lifts that move aircraft from the hanger deck to flight deck. One lift can lift up to 40 tons and 20 tons the other.
