Stellar-class Tactical Plasma Missile

The Stellar-class Tactical Plasma Missile / Plasma Torpedo or known by its official designation, RSM-7 Stellar, is a level 5 to 6 WMD developed and used by the UEF Navy for their Yugumo-class Destroyers and its subclasses. Intended to enhance the combat capabilities of federation destroyers, they were capable of destroying entire opposing fleets or task forces in a single salvo of two torpedoes at once. However because of it's destructive capabilities, it was strictly prohibited from use unless in the absolute situations or authorization from high-ranking personnel
== Description ==
The Stellar-class is directly based off the Type 39 Star Lance Torpedo, with the primary change being its warhead being swapped for a significantly more powerful WPX-5 Plasma Reactive Warhead. Much like the Type 39, it is equipped with 3 compact plasma thrusters at the rear and has 8 maneuever thrusters.
== History ==
The missile/torpedo at moment has only ever seen active use once which was during the Battle of Planet Utao of the 1st Intergalactic War.
=== Battle of Planet Utao ===
During the orbital battle of Planet Utao, the RSM-7 Stellar was authorized to be used by Admiral Kine, the acting commander of the Federation 6th Fleet. Destroyer Squadron 156, one of the two federation destroyer squadrons permitted to carry the weapon followed this order and a single destroyer, the Sherman-subclass FSS Noble, fired a salvo of two Stellar Torpedoes from its forward-facing spinal mounted launchers. The torpedoes was prime to explode dead center of the opposing fleet. Imperial warships desperately attempted to intercept the two torpedoes but ultimately failed and both torpedoes exploded in the center of the fleet of over 58 warships in between a imperial battleship and cruiser. The explosion almost immediately vaporized both capital ships and destroyed 13 additional nearby cruisers, destroyers and frigates, while damaging 24 others with 10 suffering crippling damage and 4 being completely disabled.
The surviving imperial ships were quickly ordered to withdraw. However Task Force 68, an element of the 6th Fleet, resumed fire and destroyed the majority of the surviving ships with only 8 escaping and only 2 surviving the onslaught, prefering to scuttle themselves. Admiral Kine's usage of the weapon in the battle was criticized both by the Federation Council and Military Council as although the opposing hostile fleet outnumbered Task Force 68 by at least a quarter, Task Force 68 was on equal footing as it was comprised of a larger amount of capital ships than the opposition and was also supported by Carrier Group 21 from the 4th Fleet. 
The aftermath of the battle and the Stellar Torpedo's true capabilities now seen, restrictions on the weapon's usage was further strengthened and much more strictly enforced.
