Designation: Rockwell International / Bell Textron F-200 Mastiff Laser-equipped High Altitude Interceptor

I. Dimensions:

  • Length: 10.8 meters.
  • Height: 3.2 meters.
  • Wingspan: 7.5 meters.
  • Dry Weight: 11.5 metric tons.

II. Service History:

  • FL-200A Served with the UN Spacy from 2003-2009. Later re-designated F-200A.
  • F-200B: Served with the UN Spacy from 2007-2011. After 2009, the F-200 was phased out in favor of the VF-1 and QF-3000.

III. Type:

  • One-man high altitude interceptor.

IV. Propulsion:

  • Main Engine: 2 x Rolls Royce variable cycle chemical afterburning hypervelocity turbojets.
  • Secondary Engine: 4 x Nakajima NBS-1 high-thrust thrusters.
  • Protoculture generator
  • 2 Protoculture cells

V. Performance:

  • Maximum speed: Mach 5.5 above 15km
  • Stall speed: 140 kph.
  • Range (typical): 1500 km
  • Maximum altitude: 26,000 meters
  • Design-g limits: 7 g
  • Powercell Endurance: 10 minutes from laser cannon

VI. Electronics:

Radar System:

  • Hughes AWG-20 X-band pulse-Doppler radar, providing long-range detection and tracking of targets at all altitudes, as well as extensive surface search, attack, navigation, and mapping modes.

Optical tracking:

  • Thomson LT-3 multi-frequency laser ranger/designator
  • Zeiss FOI-8 infra-red imaging sensor and low-light level camera system in retractable optic blister under the cockpit.

Tactical Electronic Warfare System (TEWS):

  • Elettronica Radar Warning Receiver (RWR)
  • OlDelft Infra-red Warning Receiver (IRWR)
  • Westinghouse ALQ-200 active radar jammer
  • Chaff dispenser
  • Flares
  • Active missile jammers

VII. Armament:

  • 1 x Mauser RoV-5 laser cannon capable of firing 1000 pulses per minute with a peak power 1 megawatt. The system was prone to overheating if firing maintained for too long of a duration.
  • Ventral weapons bay containing capable of holding four of the following: 178mm AIM-120C Scorpion long range missiles, 320mm Dagger long range missiles or 300mm Stiletto multi-purpose long range missiles.

VIII. Armor:

The skin of the Mastiff is composed of treated steel plate. The skin provides excellent protection against small grenade and shell fragments, good protection against small arms fire, and poor resistance to heavier infantry weapons, such as the 12.7mm machinegun round, as well as from fragments and near misses from higher caliber weapons. The Dragon provides full protection from nuclear, biological, and chemical hazards, using an overpressure cockpit environment activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions are anticipated. The internal consumables supplies can provide atmosphere for eight hours maximum.

IX. Development:

This limited production run fighter/interceptor was the first production fighter to use laser armament, (hence the ‘L’ included in the designation) with a protoculture-powered laser cannon replacing the internal 20mm M61 cannon found on most Western fighters of the day. With the mass production of the VF-1 and Destroid series, the ‘L’ designation was dropped to reduce the proliferation of nomenclature.

This small lifting body fighter contained an internal weapons bay capable of holding four missiles to complement the laser cannon. The internal carriage of weapons was a requirement, due to the FL-200’s hypersonic high altitude performance envelope. The problematic laser cannon and limited missile payload kept the Mastiff from a large production run and the introduction of the Ghost and Valkyrie fighters quickly supplanted this interceptor.
