Ndubehlzih-Class System Defence Boat

BARD PAPER: SARA004

Ndubehlzih Class System Defense Boat

Nyolenambih Inc. is proud to present you it's most recent SDB design, the Ndubehlzih. Built in our shipyards on Darrian (0627 Spinward Marches) to profit from TL:G technology, this ship is among the most powerfull of it's generation. We also expect to provide a prototype fitted TL:H Matter-Antimatter powerplant withing the next decades. A downgraded TL:F version is also available to be built in other shipyards in the regency.

Main weapon is the 2 Gj laser battery, mounted dorsally on a small bay. Secondary weapons are two 240 Mj Laser barbettes and a Missile Barbette. On defensive side, a good sized Meson screen (630 PV), EM masking, more than one thousand sensor Decoys and 81 Gturns.

As most destroyers within 10,000 dTons are equiped with meson based weapons rated over 5 Gj, this meson screen offers a protection against meson up to 11 Gj allowing the ship to survive most direct impacts with low or no damages. Also while meson based weapons are devastation a short range, they suffer a lethality degradation as range increase. The laser battery can be overpowered to 200 shots per turn (-3 diff) and the laser barbettes up to 400 shots per turn (-4 diff) if other systems are shut down.

Both laser barbettes are fitted with their own powerplant, which makes them independant from the central powerplant, and thus capable of returning fire even if the ship lose part of it's power. The missile barbette can hold any standard 7kl missiles, and several HEPlaR kinetic energy or close proximity nuclear missiles were developed (35 m³ missile storage room).

Most of ship's important systems have a backup: AEMS, PEMS, PEMS antenna, etc. It was clear that the best possible sensors would be used in this ship on the active side. The crew's comfort was thought also:one small stateroom for recreational use fitted with video equipment.

Notes

One small stateroom is provided for crew's recreational use.Total Fuel Tankage: 1932.4 m³ (135.3 tons)
Fuel scoops (10% of ship surface), fills tanks in 1.15 hours
Fuel purification machinery (0.85MW), 11.4 hours to refine 1932.4 m³.
Only 1 Radio, 1 AEMS & 1 Ladar are powered during combat,
All 4 Maser & 2 Laser Comm are powered during combat.
