Starfish-class Destroyer (DD)

Original Date of Design: 	21 Mar 2297

Fleets of Service: 		Japan

Design History

The Starfish-class destroyer was built as a replacement for Marshall Foch-class destroyers that had been license-built by Japan over the past decade. The French design had several limitations for the Japanese; lack of a dedicated hanger bay for a troop lander; inadequate troop compliment, and poor warp efficiency.

In 2297, Japanese design teams were tasked to produce the plans for a replacement escort. Several designs were submitted, but the fueling requirement of a MHD power plant proved to be a major stumbling block to endurance. A second round of designs was requested with a fission or fusion power plant. These second generation designs provided sufficient endurance, but still suffered from poor warp efficiency during combat due to the specified particle beam weaponry load. The Imperial Japanese Navy was unwilling to compromise on the weaponry load and it seemed that the end design was going to be extremely expensive, due to the large power plant needed.

In early 2299, the design bureau of Mitsumami Industries submitted an innovative design that consisted of a fission power plant providing primary power and a MHD booster plant that would be used during combat to power sensors and beam weaponry. The design relied heavily on recent breakthroughs in power integration and management circuits to provide a steady power system. In September 2299, construction of the first hull began.

Design

The hull is constructed of six equal box segments attached at right angles to each other at a common center to produce a six-pointed plus symbol. The Japanese class name translates as Starfish while the American military calls it Jacks, in reference to the pieces in the common children’s game. The entire hull is spun about a single axis so that the arms in the x and y planes rotate about the two arms in the z plane. The arms in the z plane remain un spun and contain the engineering section, hanger deck, and missile bays. Each of the rotating arms is capped with a jack turret containing beam weaponry and the arms are spun down during combat to reduce damage due to sudden imbalances caused by damage.

Power generation is provided by a primary fission plant. This plant provides sufficient power to run the drive unit at full efficiency. A MHD booster plant is engaged during combat to provide power to the sensors and beam weaponry. Fuel tankage is provided to run the booster plant for five hours. Additional fuel tankage is carried that can be used to refuel the MHD plant, but the plant must be powered down to transfer fuel; a process that takes approximately thirty to sixty minutes to complete.

Notes:

  1. Turret arc values are (counter clockwise from left center): 1 bow, 2 starboard bow quarter, 3 starboard broadside, 4 starboard aft quarter, 5 aft, 6 port aft quarter, 7 port broadside, 8 port bow quarter.
  2. Combat booster plant uses regular engineering crew to control; no reduction in damage control.
  3. Combat booster plant has sufficient fuel for 5 hours of operation to power all weapons and sensors.
  4. Hull Hit Capacity has been determined using the formulas presented by KevinC on the 2300AD Mailing List on 10 Oct 1997, where the standard calculation has been modified by the use of the cube root of the armor level instead of armor level to the first power.Therefore: Hull Hits = Material Volume * (Armor level)^(1/3). This makes more realistic hull hit capacities.

Arrows of Nykai-class Fighter (FTR)

Original Date of Design: 	13 Mar 2297
First Example Laid Down: 	20 Aug 2298
First Example Completed: 	24 Mar 2299
Fleets of Service: 		Japan

The Arrows of Nykai-class fighter was constructed in 2299 by the Japanese, with French assistance. A fast fighter, the Arrows of Nykai, relies solely on missiles for its weaponry, carrying two Ritage-2 missiles in magnetic slings. The Weapons Officer can control one missile at a time although the two may be fired together, with control of one or both handed off to another ship. The fighter has no defensive weaponry, and relies on the skill of the pilot, armor, and stealth characteristics to minimize damage to the craft. The Arrows of Nykai-class is fully streamlined, but this is reduced to partial streamlining when missiles are present. Booster units are used in most cases to assist the fighter in leaving orbit when carrying missiles.

The Arrows of Nykai is one of three fighters designs put into production by the Japanese space forces. Each design is unique in its weaponry-submunitions for the Soaring Dove, missiles for the Arrows of Nykai-class, and beam weaponry for the Rainbow Sword-class.

Rainbow Sword-class Fighter (FTR)

Original Date of Design: 	13 Feb 2299
First Example Laid Down: 	04 Aug 2299
First Example Completed: 	12 Dec 2300
Fleets of Service: 		Japan

The Rainbow Sword-class fighter was constructed in 2300 by the Japanese, with French assistance. A fast fighter, the Rainbow Sword is a traditionally gunned craft with a duel beam turret controlled by the Weapons Officer. The last of the three designs constructed by the Japanese, it shares little in combination with the other two except for similar speed performance. The Rainbow Sword-class is a more massive dual engine design with extensive hull masking to offset the increase in radiated signature.

The Rainbow Sword is one of three fighters designs put into production by the Japanese space forces. Each design is unique in its weaponry-submunitions for the Soaring Dove, missiles for the Arrows of Nykai-class, and beam weaponry for the Rainbow Sword-class.

Soaring Dove-class Fighter (FTR)

Original Date of Design: 	31 Jan 2297
First Example Laid Down: 	23 Apr 2298
First Example Completed: 	06 Dec 2298
Fleets of Service: 		Japan

The Soaring Dove-class fighter was constructed in 2298 by the Japanese, with French assistance. A fast fighter, the Soaring Dove, relies solely on submunitions for its weaponry. The lack of high powered weapons and an active sensors array allowed for the power plant size to be kept to a minimum and reduce the weight of the craft. Moderate armor and stealth characteristics, coupled with the small size of the fighter make it difficult to target.

The Soaring Dove is one of three fighters designs put into production by the Japanese space forces. Each design is unique in its weaponry-submunitions for the Soaring Dove, missiles for the Arrows of Nykai-class, and beam weaponry for the Rainbow Sword-class.
