The T-900 is a high supersonic anti-ship and surface to surface missile developed by Alderia Armaments, based mostly on the T-890, it has been vastly improved with increased speed capacity, an autonomous targeting and guidance system and improved jamming capabilities. It currently stands as the longest ranged anti-ship missile in service with Tarsas with a maximum range of 580km.
Design
Unlike current anti-ship missiles the T-900 is capable of conducting autonomous targeting, relying on on-board targeting systems to independently acquire the target without the presence of prior, precision intelligence, or supporting services like Global Positioning Satellite navigation and data-links. These capabilities enable positive target identification, precision engagement of moving ships and establishing of initial target cueing in extremely hostile environment. The missile was designed with advanced counter-countermeasures to effectively evade hostile active defense systems.
The T-900 is based on the T-890, but incorporates a multi-mode radio frequency sensor, a new weapon datalink and altimeter, and an uprated power system. It has a increased range than the T-890, yet it covers the increased range and speed with a heavier weight. It can be directed to attack enemy ships by its launch platform, receive updates via its datalink, or use onboard sensors to find its target. T-900 flies towards its target at medium altitude then drop to low altitude for a sea skimming approach to counter anti-missile defenses.
T-900 is designed to be compatible with Tarsan VLS systems used on many Imperial Sea Legion ships and to be fired from aircraft, including the various heavy bombers employed by the Legion. For surface launches, T-900 will be fitted with a modified Type 66 jettison-able rocket booster to give it enough power to reach altitude. The missile is prominently deployed on the Imperator class cruiser and Veros class cruiser
T-900 Service types
Since 2009, the design team discovered that the weight of the missile and speed effected its functioning altitude. In response they designed two 'Service Type' versions of the missile. In 2010, Alderia unveiled it's two types. Each designated by its altitude capabilities, each changing it's range and possible speed.
T-900L
The T-900Low as it is called, is the sea-skeaming capable version of the T-900. It's cruising altitude is that of 5-10m above sealevel, however it's ranged has been reduced from 435km maximum to 325km, still 25km further than the T-330 which is the current mainstay of the Papal Navy's anti-ship missile inventory. The T-900L also has a reduced weight of 2,200kg and has a warhead of 280kg. It maintains the same guidance systems and may be operated on all Rodarian naval vessels. It may reach a speed of Mach 3.1.
T-900H
The T-900High is the high altitude version of the T-900. It operates at an altitude of 15,000 meters and may reach mach 4.9. It carries the 453kg warhead and weighs 3,250kg and may only be operated aboard cruisers and heavy naval bombers. During its final phase, the T-900H drops from 15,000 meters to 12 meters and makes it's final run against it's target. It maintains the same guidance system.
Additional Variants
These were other modifications done by Anacom Industries under license.
P-900T.A
The T.A was the first variant to emerge from the factory. The variant was specially designed for use aboard the Imperator class cruiser. The guidance computer was totally redesigned. Combining inertial navigation with constant instructions from the home ships radar or a GPS satellite, the system has a high accuracy rating. The computer can also switch the guidance to an infrared homing pattern. With aircraft and steel comprising the decks of most carriers, they make a very large heat source. If the missile is near its target, the guidance can be swapped mid flight by the home vessel and the missile can lock onto a heat source. In the event the missile is jammed and unable to receive instructions from a friendly source, the guidance computer locks onto the source of the jamming device in an attempt to destroy it. This was shown to cripple a ship very quickly with multiple jammed missiles locking onto a vessel that is jamming multiple missiles. The 900T.A can only be used at high altitudes and with it's flight path, that's the only altitude it needs to operate at. Instead of a ramjet, the missile is equipped with a scramjet. The scramjet is much faster and much more capable than it's ramjet countepart as long as the missile keeps it's speed high. The 900T.A is larger than the standard missile because of a thrust increase to the two stage rocket system that launches the missile. The missile operates it's rockets until it hits 18,000 meters. It will then use a scramjet to reach it's top altitude of 23,000 meters. When the missile gets within final approach range of it's target, it aims towards it's target and rapidly accelerates with it's remaining scramjet fuel. With the increased engine output, initial tests showed the missile being able to reach up to Mach 6 at full speed. By this stage, the kenetic force alone would be massively damaging. The missile packs a punch, however, with a 350kg shaped penetrator for the warhead. The penetrator also has a titanium core to protect the penetrator from a hard impact. A nuclear warhead variant exists as well, though none have ever been tested.
P-900T.B
The T.B spawned out of a request by the Air Legion and Coastal Legion to acquire an air launched variant capable of being utilised on the AT-4 heavy bomber platform. The missile uses a high altitude attack pattern. The two stage booster system is swaped for a single stage booster. The scramjet from the T.A is maintained as the primary means of propulsion. The missile launches and uses it's single stage booster to reach supersonic speeds. The missile has several directional jets in it's nose cone that make adjustments on the missile's course before the scramjet activates at Mach 4. This particular missile contains an active radar system that activates on que with the final approach. The radar tracks the specified target. This particular feature was added to compensate for the lack of guidance from the launching source. It gives the launching aircraft the option to move out of the area if necessary. This variant also has the capability to lock into the source of anything that tries to jam it and target that if necessary. The missile's mounting system uses a standard Tarsan aircraft rail mount but can be quickly adapted to other mounts.
P-900T.C
The T.C was the third development of the missile. Designed specifically for the submarine force, the missile is capable of being launched underwater as long as the sub is sitting close to the surface. The missile is equipped with a regular ramjet instead of a scramjet. The change in propulsion was due to the fact that the attack pattern is low altitude sea skimming, this significantly decreases the missile's range to a low 200 kilometers compared to it's max range of 500 kilometres for high altitude flight. This also cancels out the speed boost. The missile uses a similar guidance system from the T.B. It is designed to operate independently from the source. It has it's own active radar and can directly receive instructions from a GPS satellite. Like both of it's other variants, the T.C is capable of locking onto the source of a jamming device and changing its target to destroy missile jammers. This variant also has a capsule launch system in place for covert missile strikes. The capsule is a fully capable launch device that holds one missile. These capsules can float and be released from submarines especially prepared to carry them. They can float to the surface and operate off instructions input before launch. The capsules have limited movement capability. It can receive GPS data on a target and be programmed to launch at a specific time. The capsule system has the advantage of being able to launch a complete surprise attack on an unsuspecting vessel. However, it cannot launch at all under the conditions of a radar jammer because it cannot input target data into the missile. The capsule system is deployed only occasionally with most T.Cs being launched from a submarine.
