Broadsword Ultra-Heavy Torpedo
Background With the rollout of new ultra-heavy torpedoes by Omzian defence corporations and the development of the new Tyrant-class submarines by Freethinker Defence Industries, Windham & Green Defence Industries engineers were contacted to design a new ultra-heavy torpedo for use against the massive superdreadnoughts and large battleships in the world's navies. With the assistance of several engineers from Omzian companies and the Portland Iron Works, Windham and Green has developed the new Broadsword 1,000 mm ultra-heavy torpedo. After performance assessments, the Incorporated Sarzonian Navy looks to adopt the torpedoes and will reclassify its current stock of torpedoes.
Design Information Capable of either conventional or nuclear armament, the Broadsword has been designed to serve as a devastating opponent to any enemy's large warships. To pack the enormous destructive power into a single torpedo, the standard Broadsword torpedo measures a full 14.5 metres in length, or 47.6 feet. With its one metre diameter, it dwarfs the previous ultra-heavy torpedo employed by the Incorporated Sarzonian Navy, the Bayonet, which is expected to be reclassified as a heavy torpedo. A vertical launch variant measures 13 metres, or 42.7 feet and can be cold launched from a deep draft submarine currently under development by the Portland Iron Works. The Broadsword measures a full 20,000 kg, just over 22 tonnes with a warhead weight of 3,000 kg. It can be used for a fast attack against a large enemy warship with a range of 35 km at 75 knots or at longer range, 100 km at 40 knots. Used in conjunction with the deep draft submarine employing a towed sonar array and an unmanned underwater vehicle (UUV) sending false sonar readouts to enemy submarines, and you have a potentially lethal combination to any size of warship.
Guidance and Propulsion To ensure that the Broadsword is not simply an oversized mine and easy pickings for an enemy battlegroup, the torpedo uses a turbine-powered pumpjet propulsion system. As mentioned earlier, the Broadsword can be cold-launched from extreme depths by a submarine or it can be horizontally launched from very large warships. The Broadsword employs an active/passive sonar guidance system for terminal guidance and is initially guided toward its acquired target by the towed sonar array in the submarine.

Loch Ness-class heavy SSGN
Background In the process of developing the new Broadsword ultra heavy torpedo for the Portland Iron Works and the Incorporated Sarzonian Navy, PIW engineers realised they didn't have a underwater platform that could be readily equipped to employ the new torpedo from horizontal tubes, to say nothing of the requirement to arm the vertical launchers for such a submarine. Consideration had been given briefly to simply adopting the Freethinker Defence Industries Tyrant-class SSBN, but issues such as the Domestic Defence Appropriations Act and Sarzonia's reluctance to employ a warship class named Tyrant led the PIW to begin the groundwork for a submarine of its own. The result is the Loch Ness-class heavy SSBN.
Design Details To create the Loch Ness, the PIW realised it needed a much lengthier hull to allow the submarine to employ the large number of vertical tubes necessary for its task as an anti-battleship/SD platform. As a result, the Loch Ness dwarfs the venerable Steadfast-class SSBN/SSGN by a full 80 metres, making its length a full 235 metres. In addition to the requirement for greater length than anything the PIW previously employed underwater, the beam also had to increase to allow for the wider dimensions of the Broadsword. As a result, the beam increases to a full 21 metres. To promote survivability, the Loch Ness employs a revolutionary triple hull surrounding a honeycomb frame with the outer hull being amorphous steel covered with anacheoic tiles to retard an enemy's ability to detect the submarine. The middle hull armour is an alloy of titanium, vanadium and aluminum, which provides nearly unparalleled protection against many weapons types. The inner hull is designed with a combination of biosteel and ballistic ceramics to provide additional protection against weaponry. The increased emphasis on protection, even over and above Sarzonian requirements for optimum survivability, is not merely intended for the submarine to survive weaponry. The operational profile of the Loch Ness dictates that the sub remain at extreme depths beyond the range of most passive sonar readouts; thus, allowing it to sneak up on any enemy's ultra large warships.
The result of this is a submarine that displaces 67,500 tonnes submerged, and with the heavy weight comes a need for massive power to propel the submarine through the depths. As a result, two specially-modified Pebblebed nuclear reactors have been provided to generate the power necessary for the Loch Ness to travel at speeds approaching 35 knots submerged. However, with an eye toward stealth travel, engineers also included a magnetohydrodynamic drive (MHD or "caterpillar" drive) to propel the submarine in an all but completely silent mode of travel. Engineers have determined, however, that the sub can only employ the MHD drive at speeds of no greater than nine knots. At the higher rates of speed, the submarine generates significant noise that even the acoustic dampening functions of the anacheoic tiles can not compensate for.
Armament The Loch Ness is among the standouts in the new realm of ultra large submarines due to an extensive vertical launch armament of 108 one metre tubes, making it capable of launching the vertical launch variant of the Broadsword or the current Scourge or Scorcher missiles currently employed by the Incorporated Sarzonian Navy. In addition, the Loch Ness employs four 1,000 mm torpedo tubes that allow it to fire the horizontal variant of the Broadsword. However, the Loch Ness often employs no more than 10 or 12 of the horizontal variants, allowing the Silver standard (21 inch; 533 mm) torpedo or the Bayonet heavy torpedo (26 inch; 650 mm) to be employed depending upon the mission profile. The Loch Ness normally employs the Silver for most missions when a lighter torpedo is sufficient, though the Bayonet can easily be fitted.
