Avia Phosphor

History
The Phosphor was originally conceived by Albiz Aviawerk's chief designer Endymion Wihtred, a specialist in supersonic aircraft, for a long-range supersonic combat aircraft that could achieve exceptional agility, a conclusion he reached through his work on supersonic transport aircraft. Wihred's proposal was initially pursued by Albiz's parent company REST with its own funds but failed to attract interest from the Austrasian Luftwehr. This situation changed in the late 80's when the Luftwehr developed a new concept of ultra-long range air battle that envisioned using to guide Ground Alert Interceptors into air engagements over Goetia, a concept it was argued would allow the heavily outnumbered Luftwehr to inflict disproportionate damage to the Goetic air force and help forestall a Goetian attack on Boaga preventing by extension an attack on Austrasia itself. Wihtred's concept attracted the interest of the Luftwehr, its high cost notwithstanding, because of his track record as a successful designer of and the extensive benefits to Austrasian industry promised by REST's ambitious technology proposals, including an exotic turboramjet engine.

Concept of Operations
The Phosphor is operated in five squadrons of twelve aircraft by the Luftwher which maintains them on continual high alert status, each aircraft is assigned three flight crews one of which is on alert suited up inside the aircraft at all times, enabling the aircraft to lift off in under five minutes at any time. A further sixteen aircraft were completed and are held in storage by the Luftwehr to make up for future attrition and if necessary to replace aircraft in squadrons needing significant maintenance. The Phosphor's turboramjet engine, a turbojet engine nested inside a ramjet, can provide thrust from zero speed with the engine transitioning from turbojet to ramjet operation at Mach 3.25. Takeoff thrust can be further augmented by an optional water-injection system using a special discarding water tank. In its cruising condition, the Phosphor has exceptional maneuverability for its speed being capable of sustaining a 2G turn at Mach 3.5, making it a difficult target for any would-be interceptor or SAM.

Fighter Sweep
The principal mission of the Phosphor is a deep in hostile airspace over airfields in Goetia. With overall control and situational awareness provided by long-range located in Austrasia. For this mission the Phosphor is typically armed with eight compact  missiles. Primarily intended to engage enemy aircraft the missiles can also be used to attack unarmoured targets - such as parked aircraft - by flying a dogleg trajectory and employing a homing mode. The missile is also capable of homing in on the radar emissions of high-frequency radar typically used for fire control by aircraft and surface-to-air missiles giving the Phosphor a degree of capability. The missile has no conventional warhead but incorporates a small explosive charge intended to fracture it into a number of large fragments. This, together with the energy released by its inherently high impact speed, is considered sufficient to destroy unarmoured targets ranging from aircraft to surveillance radars. So armed the Phosphor is capable of engaging aircraft however it encounters them, in the air or on the tarmac.

Airfield Attack
An important class of targets the Phosphor cannot engage with its baseline armament is. For engaging aircraft protected in shelters the Phosphor can carry up to four 500lb low drag, rocket-boosted. The bomb is armed with thick walled high explosive warhead fused to explode after penetrating deep into concrete, rock or earth. Though intended to destroy sheltered aircraft they can also be used effectively for cratering runways or destroying bunkers including command centers and magazines at airfields. During an attack mission, the Phosphor primarily relies on its primary radar operating in mode to image the target area allowing it to both find the targets and generate guidance imagery for the bombs scene-matching terminal guidance system.

Point Defense
An alert Phosphor can reach its cruising speed and altitude within 12 minutes of receiving a launch order.
