The Leda II (Japanese: レダII) was an Alliance cruiser which was notable for being the ship that Yang Wen-li died on.


Service history

The Leda II's first notable mission was under the command of Commander Zeno. It was the ship that Admiral Yang Wen-li chose to travel with from Iserlohn Fortress to Heinessen in 798 UC (489 IC / 3598 CE), for an extra-legal 'inquiry'. When the Imperial fleet and Geiersberg Fortress attacked Iserlohn in Yang's absence, the Leda II took him back, serving as flagship of the small fleet of 5000 ships sent as reinforcements. In the ensuing battle, the Leda II was struck by enemy fire, but its shields held. (LOGH: 'The Inquiry Committee', 'Fortress vs Fortress', 'The Return')

In July 799 UC (1 NIC / 490 IC / 3599 CE), the Leda II also ferried Fleet Admiral Yang and his comrades off of Heinessen. (LOGH: 'Blood Running Down the Stairs: Cascade')

The Leda II eventually became part of the El Facil Revolutionary Reserve Force, which fought the combined fleets of Kaiser Reinhard at the Battle of the Corridor in 800 UC (2 NIC / 491 IC / 3600 CE). When a truce was called and the Kaiser invited Yang for talks, Yang once again elected to take the Leda II. Representatives from the El Facil Revolutionary Government also attended. A Terraist ploy resulted in the ship being boarded by Terraist-controlled Imperial destroyers en route, and a slaughter ensued as the assassins hunted for Yang. With Yang's subordinates having been informed of the threat to his life soon after the Leda II's departure, the flagship Ulysses managed to catch up to the Leda II's position. Julian Mintz and the Rosen Ritters were too late, and Yang was assassinated. The Leda II was then evacuated. (LOGH: 'The Magician Doesn't Come Back', 'After the Festival')

The development of the Brünhild came as a considerable shock to the Free Planets Alliance. Initial intelligence reports had reported construction of a new Imperial flagship using new curved armour plating technology, but Alliance projections anticipated a ship similar to the Forseti. The final appearance therefore of the Brünhild with its gleaming white coating came as a major shock. In response the Alliance resolved to also develop its own ship designs using curved armour technology, and decided to start with a new cruiser design. (Fleet File Collection Vol.9)

The main armament consisted of 4 neutron beam cannons. Though the number was less than the old standard cruiser design, these used new high performance particle accelerators and were superior to the old design in range, accuracy, and destructive power.

On each side of the bridge tower, a series of 11 low-calibre high rate of fire electron beam cannons were installed to defend against enemy fighters. Simulation testing showed good results. (Fleet File Collection Vol.9; Data Book: Mechanic & Seiyū Encyclopaedia, p. 139)

The main engines were new high thrust engines with a wide range of variable thrust output settings. An improvement of 40% or more in thrust output was achieved over the old standard cruiser engines. The downside was increased propellant consumption. To combat this, two enlarged pure water tanks were placed aft of the bridge and Bussard ram fuel scoops, previously only mounted on Ajax class flagships, were included in the design. The intakes were located on either side of the forward hull section and bear resemblances to the red-coloured intake ports on larger Alliance flagship designs.

The Spartanian fighter complement used the hangar located aft of the bridge above the main engine instead of the half open hangar design used on the old standard cruiser design. This switch reduced the potential risk of secondary explosions and chain reaction in case of damage.

Only a small number of this new cruiser design had been produced on a trial basis by the time of the dissolution of the Free Planets Alliance. (Fleet File Collection Vol.9)

Fleet File Collection

The Leda II is included as a model in Fleet File Collection Vol.9. In a 'Reader Memo', it is mentioned that the 'Brünhild shock' (mentioned above) was analogous to the 'Dreadnought shock' on warship builders of the early 20th Century caused by the revolutionary design of the Dreadnought.
