BACKGROUND
Powerful and versatile with the capability to operate
anywhere in the world, the Type-23 Frigate is the mainstay of the Royal Navy
Surface Fleet, forming 50% of the total Frigate/Destroyer force. Originally
designed as cheap replacements for the Leander class frigates for Anti-Submarine
warfare, the Frigates weapon systems and adaptability allow it to operate
anywhere in the world at short notice fulfilling multiple roles including both
Anti-Submarine, and Anti-Air Defence. The Falklands War of the early 1980's
taught the Royal Navy many hard lessons which resulted in the inclusion of
additional weapons on its Surface Vessels, and enhanced stealth designs to
reduce their radar signature. Along with its main propulsion system (CODLAG)
permitting it to run nearly silent at times the survivability of the Frigate is
enhanced. The Type-23 Frigate is less susceptable to the Anti-Warship Exocet
Missiles used so effectively by the Argentine Navy and Air Force against the
Royal Navy Fleet.
These include embargo operations using boarding teams inserted from the
ship's boats or helicopter, disaster relief work and surveillance operations.
HMS Norfolk was the first Type-23 Frigate to enter service in the
Royal Navy's Surface Fleet on the 1st June 1990, and since then 15 others have
also joined the Surface Fleet, with 4 more planned. To better assist the Type-23
in its missions it carries a single Merlin Helicopter. Formerly carrying a Lynx
Helicopter the Type-23's Lynx's were replaced by the Merlin in 2001. The
combination of the Lynx/Merlin with a Type 23 ensures that the Type 23s are one
of the most capable units in the world. The Type 23 Frigates are also the first
Royal Naval vessels to carry the VL Sea Wolf system. Seawolf is an anti-aircraft
and anti-missile system. It is highly potent, with a closing speed in excess of
Mach 2. The advantage of the VL Sea Wolf is that there are no blind spots, and
it is capable of firing throughout 360 degrees.

NOTES:
- Depleting the MDC of the main body will put the Frigate 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 Frigates 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.

WEAPON SYSTEMS:
- 4.5 INCH (114MM) MK8 VICKERS CANNON (1): The Royal Navy decided to
re-introduce Cannons to their Surface Fleet Vessels after the hard learnt
lessons of the 1981 Falklands War. Instead of a cumbersome 6 inch Gun with a
slow rate of fire the Royal Navy chose a slightly smaller Gun with a higher
rate of fire as their main defensive weapon.
- PRIMARY PURPOSE: Anti-Ship/Surface targets
- SECONDARY PURPOSE: Anti-Aircraft
- RANGE: 14 miles Versus Surface targets / 5 miles Versus Airborne
targets
- DAMAGE: 3D8 x 10 M.D.
- RATE OF FIRE: 12 rounds per melee
- PAYLOAD: 16 rounds on a ready rack with more stored below.
- NOTE: Several other types of ammo can be selected: Chaff,
illuminating, and practice rounds
- VERTICAL LAUNCH SYSTEM SEAWOLF LAUNCHERS (32): The primary
anti-aircraft weapon of the Type 23 Frigates. These thirty-two SAM Pods are
designed to provide saturation fire against air threats, both aircraft and
missiles after the Royal Navy lost so many ships to Exocet Missiles during the
Anglo-Argentine War over the Falklands Islands. The Missile batteries are
located forward of the bridge right behind the MK8 Gun.
- PRIMARY PURPOSE: Anti-Aircraft
- SECONDARY PURPOSE: Anti-Missile
- RANGE: 5 miles
- SPEED: Mach 2.5
- DAMAGE: 4D6 x 10
- BLAST RADIUS: 50 feet.
- RATE OF FIRE: Volleys of 2-15 missiles.
- PAYLOAD: Each launcher holds 1 missile. Once the rockets are
expended the launcher is empty and must be replenished.
- MK 141 HARPOON MISSILE LAUNCHERS (8): These are the principle
Anti-Ship Missile Batteries aboard ship and are carried in two launchers,
(featuring 4 tubes each,) behind the main VLS battery forward of the bridge.
They are designed to protect the Frigate and the rest of the Fleet that it is
attached to by taking out enemy ships at long range before they can get to
close to pose a higher threat.
- PRIMARY PURPOSE: Anti-Warship
- MISSILES TYPE: Self-guided missiles
- RANGE: 92 miles
- SPEED: Mach 0.9
- DAMAGE: 2D4 x100
- BLAST RADIUS: 150 ft
- RATE OF FIRE: Volleys of 1, 2, 3, 4, 8
- PAYLOAD: 1 missile per tube. 8 missiles in total
- BRITISH AEROSPACE/OERLIKON 30MM CANNON (2): As part of the close in
defence complement this weapon is designed to engage aircraft and missiles. It
is manned by a gun crew and is very effective againest low flying aircraft.
- PRIMARY PURPOSE: Anti-Missile
- SECONDARY PURPOSE: Anti-Aircraft
- RANGE: 1 Mile (1.6 KM)
- DAMAGE: 3D6 M.D. per 10 round short burst
- RATE OF FIRE: Equal to the controller's number of hand-to-hand
attacks. If set on automatic by the Principal Weapons Officer it can fire up
to 4 bursts per round.
- BONUSES: +2 to hit aircraft/mecha
- 324 MM STINGRAY TORPEDO LAUNCHER TUBES (4): The primary
Anti-Submersible weapon of the Type-23 Frigates. The torpedo launcher tubes
fire heavy warhead torpedo's designed to destroy submarines, and/or sea based
installations with a single torpedo.
- PRIMARY PURPOSE: Anti-Submarine
- SECONDARY PURPOSE: Assault
- RANGE: 5 miles
- DAMAGE: 1D4x100 M.D.
- BLAST RADIUS: 50 feet.
- RATE OF FIRE: 1 per torpedo per launcher per round. Volleys of 1
to 4 torpedo's per volley.
- PAYLOAD: Each torpedo tube holds 1 torpedo. Once a torpedo has
been launched the automated loading system reloads the tube. The reload
system holds 5 torpedo's per launcher.
- THALES DEFENCE'S SCORPION ECM/UAF-1 ESM JAMMER 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.
- HUNTING ENGINEERING SEA GNAT CHAFF/FLARE DECOY DISPENSORS (4): The
Frigates Counter-measures dispensors consist of four 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.
SYSTEMS OF NOTE:
- ELECTRONIC COUNTERMEASURES (ECM) "STEALTH" SYSTEMS: The Type-23
frigates are designed to give a much smaller radar profile due to their
design. This design makes it difficult for enemy radar and tracking systems to
determine presicely what they are and where they are. The stealth design gives
the Frigates a +2 to dodge, +1 to strike and +1 on initiative in combat WITH
OTHER NAVAL VESSELS ONLY. Aircraft are not affected by these designs.
- LIFE SUPPORT SYSTEMS: The Frigates have sufficient Food, water,
fuel and amenities to support up to 200 people for up to 6 months. In an
emergency the Frigate can support up to 400 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 Frigate 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 frigate 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.
- ENGINES: The Frigate features eight engines, consisting of two
Rolls Royce Spey SM1A 34000 HP Gas Turbine engines, two Alstom1.5 MW 4400 HP
Electric Motors, and four GEC-Alsthom Paxman Valenta 12 RP2000CZ, 7000 hp
- DECOYS: Sea Gnat (Outfit DLB) decoys and a Type 182 towed torpedo
decoy. The Sea Gnats are mounted on Hunting Engineering 130mm six-barrel
launchers for Anti-Torpedo defence.
AIRCRAFT COMPLEMENT (STANDARD):
- Lynx or Merlin Helicopter: 1
