U.S. Coast Guard Harriet Lane class Medium Endurance Cutter:


the second and third decades of the Twenty-First Century, the older Reliance and Bear class cutters were replaced with a new medium cutter class. The design was known as the “Offshore Patrol Cutter” and these vessels were quite a bit larger than those classes and rivaled high endurance cutters in size. A total of around two dozen of these vessels were built.


The Twenty-First Century was a time of military tensions with the Soviet state being reborn along with problems in the Asian Pacific theater. With the United States navy becoming stretched, it was decide to expand the Coast Guard forces to deal with the domestic realm. Along with high endurance cutters, the number of medium endurance were built. There were development plans for new advanced designs but to reduce development delays, it was decided to base the new class off the previous cutter designs.


 The class of medium coast guard cutters was named for Harriet Lane, niece and official hostess of President James Buchanan. Several previous cutters had been named for her. Even though several new coast guard classes had entered service since these medium cutters had been built, there were no real plans to retire this twenty-five strong class of medium cutters. As a result, they all remained in service when the Earth was transformed with the coming of the Rifts.


As far as engineering, there had been one major development since the construction of the new cutters. This was in the high strength composites and alloys. This allowed vessels to withstand far more damage as well as being virtually immune to corrosion. As a result, there was some delays incorporated these new materials in the new medium coast guard cutter design.


Initially, these medium cutters were powered by four powerful diesel engines. The four turbo charged diesel engines gave a range of almost ten thousand nautical miles at economical speeds and with a top speed of around twenty-six knots. Later, with the introduction of fusion power plants, a pair of light fusion plants replaced the four diesel engines. Producing similar power, the speed of the cutter is basically unchanged. Still these fusion plants gave the cutter virtually unlimited range further blurring the line between high endurance and medium endurance cutter designs.


As built, these vessels were comparatively lightly armed when compared to most naval vessels. Weaponry was a single 57 mm cannon in the bow, a single 20 mm Phalanx CIWS above the hanger. On the sides of the cutter, a pair of .50 caliber machine guns are also often mounted as well. While the 57 mm cannon was not replaced, the 20 mm Phalanx mount was replaced in later upgrades with a “Sea Sabre” mounts. This mount carries a rail gun along with short range missiles. The .50 caliber machine guns were replaced with medium rail guns as well. These rail guns are identical to the main of the SAMAS power armor. Of course, the crew is also usually armed with small arms and body armor, usually U.S. Navy surplus gear.


Electronics are more sophisticated than previous vessels with the EADS 3D TRS-16 (SPS-75) Air Search Radar being the heart of the new systems. A phased array medium range radar, it has a range of up to around 180 kilometers. Other system include an SLQ-32 electronic warfare suite and a missile decoy system. In the stern, a container can be carried with a towed array sonar for anti-submarine warfare although is rarely carried. Otherwise, limited to a short range hull sonar. The cutter has a pair of towed torpedo decoys as an additional self defense system.


Compared to older vessels, these are designed to operated with much smaller crew compliments. They are designed to operate with a crew of around sixty. In addition, they are designed to carry a troop compliment of thirty-two, usually coast guard personnel as well. In later services, six power armors were often embarked. Due to lack of Semper-Fi power armors, usually PA-04A SAMAS power armors embarked when carried although the more advanced marine power armor may be embarked on occasion. In addition to a single place hanger, the medium cutter is designed to carry a large number of small boats. In early service, a helicopter was embarked but in later service was replaced by a Kingfisher VTOL.

Power System: Nuclear Reactors, average life span is 20 years

Market Cost: Not for Sale but if found on the black market would probably cost 50 to 60 million credits.


WEAPON SYSTEMS:

  1. One (1) BAE 57 mm Mk 110 Cannon: A very rapid firing weapon, with a rate of fire of over 200 rounds per minute, but relatively short ranged. The cannon is mounted on the front of the vessel. This weapon is an original weapon system and was carried on many Naval vessels until well into the twenty first century. The guns can be used against other ships, ground targets, aircraft, and even missiles. Has a +2 to hit on 10 round bursts when using high explosive or plasma on aircraft or missiles.

    Maximum Effective Range: 5.2 miles (4.5 nautical miles/8.3 km) for standard projectiles

    Mega-Damage: High Explosive: 5D6 with 6 ft (1.8 m) blast radius per single shot and 3D6x10 M.D.C. with 30 ft (9.1 m) blast radius for ten round burst. High Explosive Armor Piercing: 1D4x10 M.D.C. with 2 ft (0.6 m) blast radius per single shot and 4D6x10 M.D.C. with 10 ft (3 m) blast radius for ten round burst. Plasma: 1D6x10 M.D.C. with 8 ft (2.4 m) blast radius per single shot and 6D6x10 M.D.C. with 40 ft (12.2 m) blast radius for ten round burst.

    Rate of Fire: Equal to Gunners Hand to Hand (Ten round bursts count as one attack).

    Payload: 880 rounds. Ship normally carries usually carries 260 High Explosive, 260 High Explosive Armor Piercing, and 260 Plasma.

  2. Two (2) USA-M31 Medium Defense Rail Guns: These weapons are mounted with one on either side of the superstructure for defense against small boats and similar roles. Originally M2HB .50 Caliber Machine Guns were fitted in these locations. These rail gun mounts were identical to those carried on the SAMAS power armor. The rail gun has fewer bursts and is heavier but the rail gun inflicts more damage than the post Rifts C-40R.

    Maximum Effective Range: 4,000 feet (1,200 meters).

    Mega-Damage: A burst of 40 rounds does 1D6x10.

    Rate of Fire: Equal to combined hand to hand attacks of gunner.

    Payload: Each has a 4,000 round magazine for 100 bursts.

  3. One (1) Mk 44 “Sea Sabre” Combination Anti-Missile Defense Systems: Mounted above the hanger and replace the original 20 mm Phalanx CIWS mount. 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.)

    Damage: Rail Guns: 3D4x10 MD per burst of 40 rounds (Can only fire bursts). Short Range Missiles: As per short range missile type (See revised bomb and missile tables for details.)

    Rate of Fire: Rail Guns: Six (6) attacks per melee. Short Range Missiles: Two (2) attacks per melee, can fire one at a time or in volleys of two (4) or four (4) short range missiles.

    Payload: Rail Guns: 8000 rounds (200 burst) each. Short Range Missiles: Sixteen (16) short range missiles each.

  4. Two (2) Chaff Launcher: Located on the superstructure of the ship, they are designed to confuse incoming missiles. Both launchers must be operated or effects will be reduced. Reduce effects of launchers by 50% per launcher not used. Rifts Earth decoy 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.)

    Range: Around Ship

    Mega Damage: None

      01-35 Missile or Missile volley detonates in chaff

      36-60 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.

    Payload: 24 each for a total of 48.

  5. Two (2) Advanced Towed Decoys: The vessel carries four advanced towed decoy drones. They are each a small automated vehicle that creates a false sonar image designed to mimic the vessels. The decoy is dragged behind the destroyer using a cable. If decoys are not destroyed, they can be recovered and repaired. Rifts Earth decoy systems are assumed to not operate against Phase World weapons due to technological difference.

    M.D.C.: 20

    Effects: The decoy has an 80% chance of fooling ordinary non military sonars and non smart guided torpedoes, the decoy has a 50% chance of fooling military level sonars (like those of the Coalition), and the decoy has a 25% chance of fooling advanced military sonars (Like those of the New Navy and Triax) and smart torpedoes.

    Range: Not Applicable

    Rate of Fire: One can be deployed at a time and requires two (2) minutes to deploy (Reel Out) another decoy

    Payload: Two (2) decoys.
