SPECTRE light vehicle

The SPECTRE is a lightweight all-terrain vehicle originally intended to replace the AM General High Mobility Multipurpose Wheeled Vehicle (HMMWV) in some roles. As development of JAMMA (later SPECTRE) progressed, the type became more focused on long range patrol and special forces type roles. According to the manufacturer, the SPECTRE is no longer marketed, and none are known to have been sold.

History
The TAC-V Joint All-Terrain Modular Mobility Asset family of vehicles has origins that date back to 2005. The vehicle was part-designed by Detroit, Michigan-based design consultancy MIDDLECOTT, and was initially promoted as a replacement for the AM General High Mobility Multi-purpose Wheeled Vehicle (HMMWV or Humvee and also as capable of internal transport by the Boeing V-22 Osprey tilt-rotor aircraft.

The rights to produce the design were acquired from California based TAC-V by the then Force Protection and was first shown publicly as a Force Protection product in February 2010 at the AUSA Winter Convention.

In December 2011 it was announced that General Dynamics (GD) had completed the acquisition of Force Protection, Inc. for around $360 m, the acquisition first disclosed in November 2011.

General Dynamics Land Systems Force Protection continued with the development of JAMMA, which by now had been ruled out of any HMMWV replacement competition as emerging requirements required more payload and greater protection. In August 2012, the design (re-branded as SPECTRE) was offered to meet the US Special Operations COMmand (SOCOM) Ground Mobility Vehicle 1.1 (GMV 1.1) requirement.

At this time GDLS marketed the SPECTRE in Narrow Track Configuration (NTC - V-22 compatible) and Wide Track Configuration (WTC – CH-47 compatible). According to GDLS the SPECTRE is no longer marketed.

Description
The SPECTRE (previously JAMMA) vehicles are designed around a modular skateboard-type chassis fitted with a modular mission adaptable body.

The original JAMMA design was internally transportable by V-22 Osprey tilt-rotor aircraft, and was demonstrated with hybrid diesel-electric drive, electric drive, and the capability to generate in excess of 20 kW of continuous export power. A wider variant that is internally transportable by CH-47 Chinook helicopter was also developed. In addition to internal transport, the Spectre was also designed to be transported as an underslung load.

The base design is modular and could be configured to suit a variety of specialist roles, these including utility, gun truck and rescue. Other options included exportable power, various winches, air compressor kits and hybrid or electric drive.

Two operators are seated behind the driver and commander, the rear platform hosting the machine gunner and at least two other personnel (maximum seating is for seven). The rear platform carries a roll-over cage that is much taller than the front part of the vehicle (for air transport the cage can be collapsed by hand in less than 90 seconds from 2.80metres to 1.82). The design offers rollover protection (ROPS) as standard, with scalable protection optional. An armour attachment system is built-in at the design stage.

Suspension is fully independent coil-sprung and of the double A-arm type. Optional mobility enhancements included run-flat inserts and a central tyre inflation system (CTIS). Quoted standard tyre size for WTC variants is 37 × 25.50R 16.5, and for NTC variants is 285/70 R17.
