Control and Guidance Systems

MEWb10-55 Processor Sets
(Four Units)
Operating in sequence all four units provide the combined control system for the torpedo, only two however are required to operate the torpedo at full capacity and only one is needed for the torpedo to function albeit at reduced capability.
Capabilities
Adaptive Guidance
While capable of direct command guidance from the launching starship, the torpedo is mostly a fire and forget system. With its myriad of sensor options and large processing power it is capable of adapting to the combat space, switching between various sensor feeds, cross referencing them, and combining images in order to determine the best mode to strike its target.
Swarm Behavior
When launched in groups of three to four or more the torpedo system is capable of data linking with the other active munitions to form 'swarms' of cooperative weapons. Effectively turning the group into somewhat of a wolfpack for hunting down and destroying targets, they will use cooperative tactics including limiting their active sensor emissions to one weapon.
Active ECM
The torpedo features an active jamming capacity which can be activated when the torpedo detects attempts at targeting it, while not as powerful as those found on ships when used in groups such as swarms of torpedoes it can be quite effective.

Armor and Structure

Structure
The Starfish-1 is constructed of a Cerrosteel hull laminated in alternating layers of Kylar Polymer and Decasteel alloy primarily to give the torpedo a rather tough and robust hull. The interior is framed with rings of Decasteel with heavy thermal shielding on the interior to protect the interior of the weapon.
Armor
50 mm Shell of 979-M Standard Military Grade Plating
-
5 mm Interior Mesh of SV90 Standard Lightweight Shielding
Active Protection
The torpedo employs a vehicle grade CFA-Type for both direct active protection against all manner of attacks against the torpedo and as a passive secondary protection against exotic energy waveforms that may cause issues with the torpedo's internal workings and electronics. It has a failure point of 2,050 Tj and comes online once the missile has been launched.
Field Refresh Rate
Every 25 Seconds

Additional Systems

Propulsion
The torpedo employs a single very large LISTM type solid fuel fusion drive system with steerage being provided by a electromagnetic/mechanical means of ducting the fusion drive's exhaust as well as small plasma bleed ducts placed strategically along the torpedo body to provide more precise maneuvering capability.

Powerplant
The torpedo's is 'cold' stored, meaning when not in use or under testing there is no power going through its systems and it will typically be linked to an umbilical to provide it as such. When in operation four NbM-95 Solid Fusion Cells, each being a five meter long rod assembly, provide primary operational power as well as the initial boost that is need to ignite the torpedo's drive. In the event of low power needs or a cold approach the torpedo employs a set of conformal capacitor packs which will store enough energy to restart the various power systems. These are typically quick charged on launch.

Warhead

(40.38 Gigatons Nominal Yield for direct KKV Impact - Vacuum Velocity Only)
Like most Pact weapons the principle and primary mechanism of destruction for the A-HAST system is simple mass times velocity, effectively simply smashing into the target at relativistic speeds often to catastrophic effect especially on targets without shielding at the time of impact. However the launching platform and the torpedo itself have two other options, the first being a 'burst' fragmentation method in which charges inside the torpedo body explode and shatter it into thousands of lethal fragments. This can be used to suppress enemy formations or target a vast surface area of a world or habitat. Finally just behind the torpedo's sensor package is a high yield callenite boosted fusion device with a RAAD or Rapid Antimatter Accelerator Device to produce the initiating AM agent for the binary warhead. This device is 'dial a yield' and capable of producing a yield of 455 Kt at the low end up to 2.5 Gigatons at the other end. While lower in destructive capability when compared to direct impact it none the less covers a larger area with its blast as well as the associated sensor blinding effects of a antimatter fusion reaction.
