Australian Perth class Aircraft Carrier:
The increasing threat of the New Soviet Navy caused the Australian government to form an unofficial alliance with the POMA (Pacific Ocean Military Alliance), comprised of Japan, South Korea, and Taiwan, in 2053. Mutual defense and combined fleet operations were major points of the agreement, and therefore forced Australia to create a truly offensive naval force. The government had considered purchasing new aircraft carriers for over twenty years. Their navy had been without an aircraft carrier for over 70 years since the HMAS Melbourne was sold to Brazil. There was serious consideration to purchasing a pair of Ark Royal class aircraft carriers from Great Britain. However, this design was considered too old and expensive to meet the Australian demands. Finally, a carrier design initially produced by the Netherlands was selected as a basis for the Australian carriers in the Twenty-Sixties. Although Australia acquired a production licence for the carriers, the Australian carrier design had many modifications to the compared to the original Dutch designs. In addition to Australia producing versions of the Dutch carrier, Germany and Spain produced modified version of the carrier as well. Australia decided to purchase four of the vessels with several modifications. One was later canceled but was later re-ordered as an amphibious support vessel.
It was decided that the ship should be able to carry fighters as well as helicopters so a full sized flight deck was decided on. It was found that the carrier was useful for not only anti-submarine warfare and convoy escort, it was found that they could be used to support assault landings as well.
These ships were fitted with fusion turbines from the beginning. These engines gave the Perth class a top speed of 32.5 knots and virtually unlimited endurance. The ships were designed with two shafts with power transmitted to the shafts via electrical propulsion. The propellers are both variable pitch allowing for faster changes in speed and the ability to turn quicker. Both the hull and propellers are designed with a bubble masking system to reduce ship noise. This is combined with the hull being covered by a sound absorbing rubber material and the engines being specially mounted to reduce noise. The end result is an incredibly quiet vessel. They were of course built using the advanced composites and alloys that were common place. This had made the ships virtually immune to corrosion and has made the ships able to withstand damage far beyond that of previous ships. The hull and superstructure incorporate radar absorbent materials and are constructed in such a way as to minimize the radar cross signature.
The ship’s armament was changes from the original Dutch design to better meet the offensive needs of the Australian Navy. As a result, the superstructure was heavily modified. In the forward part of the superstructure, a 96 cell Mk 59 VLS launcher is carried. As well, Thor class medium range missile launchers were incorporated in the carrier. American combined point defense weapon system was utilized instead of the RAM launchers and Goalkeeper mounts. The system is a combination of a rapid-fire rail gun and a short-range missile launcher. The idea is that the short-range missile launchers first engage missiles that leak through the main defense and, when they get within range, the rail guns will engage. Anti-submarine torpedo tubes are also carried on the Australia carrier.
The sensors were replaced with British units of similar make to the Dutch systems. There is a provision for a towed array sonar system but none was ever installed. The ships were designed to carry a total of 24 aircraft split between fighters and anti-submarine aircraft. The vessel has a full-length flight deck with a large hanger and ski jump forward to allow higher payloads to be carried by aircraft. In addition to the crew, these ships can carry a large number of marines. The ships can carry up to 600 marines onboard. In later service, this was reduced to 400 with 200 being in flying power armors.
Four ships of the class were originally planed but was later cut to three. Later, the fourth carrier was reordered as an amphibious command ship. When the Rifts came, HMAS Melbourne and HMAS Sydney are believed to have been destroyed while in the port at Fleet Base East, Garden Island, Sydney. HMAS Perth was the flagship for Task Force 155 in the Persian Gulf and was presumably destroyed as well.

 If Both are destroyed, no aircraft can be moved from the hangers to the main flight deck.
 If the flight deck is destroyed, VTOL aircraft can be launched or land at -15% to piloting.
 Destroying both Sampson and the S1850M Air / Surface Search System radar system will eliminate the ship’s long range air search ability but weapon systems have backup fire control systems. Both air search systems are separate so both systems are not likely to be disabled from a single hit.
 If Bridge/ Control Tower is destroyed, the ship can still be piloted from engineering but with a -15% to piloting rolls. Communication and sensor equipment are not concentrated on the bridge to reduce the effectiveness of bridge hits.
 Destroying the main body destroys propulsion and power systems, disabling the ship. The ship is fitted with an advanced polymer armor that allows the ship to withstand up to -2000 M.D.C. before losing structural integrity and sinking. There are enough life preservers and inflatable life boats to accommodate everyone on the ship.
Surface: 37.4 mph (32.5 knots/ 60.2 kph)
Maximum Effective Range: Unlimited due to fusion engines (needs to refuel every 20 years and requires maintenance as well). Ship carries four months of supplies on board.
Length: 791.3 feet (241.2 meters)
Draft: 33.1 feet (10.1 meters) including sonar dome
Width: 100.4 feet (30.7 meters) including flight deck
Displacement: 21,200 tons standard and 26,800 tons fully loaded
Cargo: 1,000 tons of nonessential equipment and supplies. Each enlisted crew member has a small locker for personal items and uniforms. Ship’s officers have more space for personal items. Extra ammo, armor, troops, weapons, and engines take up most of the ship’s spaces.
Power System: Nuclear Reactor, average life span is 20 years
Market Cost: Not for sale but if found on the black market would probably cost 1.2 billion or more credits.
- Two (2) Mk 44 “Sea Sabre” Combination Anti-Missile Defense Systems: One system
is on the front of the superstructure and one system on the rear of the
superstructure. This anti-missile defense system combines both a rapid
fire rail gun and a short range missile launcher. While mounted in one
system, both defense systems have separate tracking systems. The short
range missile launchers can target up four targets and can fire a volley
up to twice per melee. The rail gun is capable of destroying any missile
or inflicting serious damage on aircraft. The rail gun can fire on automatic
at up to six targets per melee (Has +3 to strike missile and +2 to strike
aircraft). The rail gun is very similar to those carried on the Sea King
Cruiser and it is likely that the Sea Kings rail guns came from a prototype
of this system. The system also can be used against other ships and ground
targets. The system has a 360 degree rotation and can elevate up to 90
degrees to fire at targets directly overhead.
Maximum Effective Range: Rail Guns: 11,000 feet (2 miles / 3.2 km). Short Range Missiles: As per short range missile type (See revised bomb and missile tables for details.)
Mega-Damage: Rail Guns: 3D4x10 MD per burst of 40 rounds (Can only fire burst). Short Range Missiles: As per short range missile type (See revised bomb and missile tables for details.)
Rate of Fire: Rail Guns: 6 attacks per melee. Short Range Missiles: 2 attacks per melee, can fire one at a time or in volleys of two or four.
Payload: Rail Guns: 8000 rounds (200 burst) each. Short Range Missiles: 16 short range missiles each.
- Mk 59 Vertical Launch Missile System (1): Launching cells
are located forward in front of the superstructure and bridge. The system
is similar to the vertical launch system employed on many ships in the
late twentieth century to launch the SM-2 series missile but since the
missiles are smaller they have a reload system that reloads from under
the launcher and can reload within 15 seconds. The launcher has a total
of 96 each and is eight missile cells longs by twelve cells wide. The launchers
can launch up to half the capacity of the cells per melee. The launcher
can use a vast variety of missiles including surface skimming missiles
and rocket propelled torpedoes (See Revised Rifts Torpedoes). Each cell
can carry one long range missile or two medium range missiles. The reload
for the cell must carry the same load as the main cell. Long range missiles
are normally used against large targets and aircraft further out where
the medium range missiles will normally be used to engage closer targets.
About half of all long range missiles carried are fusion warheads and most
missiles are normally smart missiles. \
Maximum Effective Range: As per long or medium range missile type (See revised bomb and missile tables for details.)
Mega Damage: As per long or medium range missile type (See revised bomb and missile tables for details.)
Rate of Fire: Can fire missiles one at a time or in volleys of two (2), four (4), eight (8), sixteen (16), thirty-two (32), or forty-eight (48) missiles per launcher per melee. Missile cells are automatically reloaded and are ready to fire next melee.
Payload: 96 missile cells in launcher with reload systems for each cell in each launcher. One long range missile or two medium range missiles may be carried per cell but reload must be the same load out as well. The ship will often carry 24 cells with two medium range missiles each and the other cells loaded with one long range missile each.
- Thor class Vertical Medium Range Missile Launchers (2): Similar
to the American Mk 55 vertical launch missile system although it fires
vertically not at a 6 degree angle to the side. The missiles are arranged
in a 2 by 4 pattern, and each launch cell has four reloads. One launcher
is mounted on the front and one is mounted on the back of the vessel's
superstructure and require less space than a Mk-41 or Mk-49 vertical launch system. Each system
can launch up to 8 missiles simultaneously each and the launcher is automatically
reloaded. These launchers often act as the ships middle point defense and
are normally used to engage incoming air targets and missiles.
Maximum Effective Range: As per medium range missile type (See revised bomb and missile tables for details.)
Mega Damage: As per medium range missile type (See revised bomb and missile tables for details.)
Rate of Fire: Can fire missiles one at a time or in volleys of two (2), four (4), or eight (8) missiles (Each launcher operates independently)
Payload: 8 missiles in each launcher, with 32 missiles in each magazine for automatic reloads, for a total of 80 Medium Range Missiles including missiles in launcher.
- Two (2) Torpedo Launchers: There is one launcher on each
side of the ship near the fantail. Each torpedo launcher has 3 torpedo
tubes and tubes are 12.75 in (324 mm) wide. Torpedoes are normally used
against submarines but can be targeted on surface targets as well. Ship
carries 60 reloads for torpedoes. Treat warheads as medium range missile
Maximum Effective Range: 20 miles (32 km)
Mega Damage: By Medium torpedo warhead type (See revised Rifts torpedoes for details.)
Rate of Fire: Can fire torpedoes one at a time or in volleys of two (2) or three (3) torpedoes per side, Reloading takes one full melee.
Payload: Three torpedoes each launcher for a grand total of six torpedoes (Has 60 torpedoes for reloads)
- Super RBOC Chaff Launcher (4): Located on the superstructure
of the ship, they are designed to confuse incoming missiles. In addition
to chaff these launchers also fired flares to decoy IR guided missiles.
Rifts Earth decoys systems are assumed to not operate on Phase World missiles
due to technological difference. Reduce effects by 20% against smart missiles
(Add +20% to rolls for smart missiles.)
Maximum Effective Range: Around Ship
Mega Damage: None
- 01-35 - Enemy missile or missile volley detonates in chaff cloud - Missiles are all destroyed.
36-60 - Enemy missile or missile volley loses track of real target and veers away in wrong direction (May lock onto another target.)
61-00 - No effect, enemy missile or missile volley is still on target.
- SLQ-25F Nixie Towed torpedo decoy (1): A special decoy which
is towed behind the ship. It generates a sound like the ship’s propellers
in order to confuse incoming torpedoes. Only effective at speeds below
18 knots. Otherwise, the noise of the ship’s systems and propellers is
too powerful to mask. Rifts Earth decoy systems are assumed to not operate
on Phase World missiles due to technological difference.
Effects: The decoy has a 65% chance of fooling ordinary non military sonars and non smart guided torpedoes, the decoy has a 35% chance of fooling military level sonars (like those of the Coalition), and the decoy has a 10% chance of fooling advanced military sonars (Like those of the New Navy and Triax) and smart torpedoes.
Decoys have a duration of 30 minutes (120 melee rounds)
Payload: One ready to use, with seven more ready to deploy. It takes three minutes (twelve melees) to reel out another decoy.
- BAE Systems Sampson Phased Array Radar System: Powerful and flexible radar system that is comprised of a single rotating array on top of the main mast. A powerful computer controls it. If allowed by the horizon, the system can track out to 175 nautical miles (201.4 miles / 324.1 km) and can simultaneously track and identify up to 480 targets at one time. The system controls missiles launched from the VLS launchers and the system tracks and guides each individual missile to a individual target for up to 120 targets. If a target is eliminated, missiles are automatically guided to a new target. The system can also control missiles launched from other linked vessels as well and can also act as fire control for gun mounts.
- Marconi/Signaal S1850M Air/Surface Search Radar: Long range air search radar system. Radar system has a range of 445 nautical miles (512.1 miles / 824.1 km). Radar system can track up to 720 targets simultaneously.
- Signaal Sirius IRST Long range infrared tracking system. Consists of two high powered passive infrared cameras capable of scanning up to 80 miles (128 km) range. Each camera is computer controlled, and the system can track 24 targets simultaneously. The system gives a +10% to read sensory rolls.
- Ferranti/Thomson Sintra 2050 sonar: Mounted under the bow of the ship. Sonar system has a range of around 24 nautical miles (27.6 miles / 44.6 km). This hull sonar system has both a passive and active system built in. Sonar system can track up to 32 targets at one time.
- Radar Defeating Profile: The ship superstructure is designed so that the radar profile of the ship is reduced. Because of this, attempts to detect the ship using radar are made with a -20% penalty to read sensor rolls when attempting to detect this ship using radar. Go to General Detection Penalties for more information on penalties and bonuses to use with stealth.
- Sonar Masking System: The Ship uses water bubbles to form a barrier against sonar combined with specially mounted engines and radar absorbing rubber hull coating. Gives a -20% penalty to any Read Sensory Instrument rolls to detect this ship using sonar.
- Combination Radar Detectors and Active Jamming System: Combination of radar detection system (ESM) and an active jamming system. The system can detect another radar system at 125% of the range of the transmitting radar. In jamming mode, causes -25% to detection but when it is active, other vehicles/ bases can detect that it is jamming, and some missiles will home in on jamming signals. Jamming also causes a -4 penalty to all radar guided weapons.
- Command and Control Facilities : The carrier carries extra communications equipment and command facilities, to enable the ship to operate as the flagship for a flotilla. When operating in a flotilla, all ships get a +1 on sensor rolls, +1 to strike on all weapons, and +10 % on communications.
