Havoc

   The Havoc was Lockheed Martin's contender to the US Marine Corps' Marine Personnel Carrier (MPC) program, which aimed to replace the LAV I-series armored vehicles for use in the light amphibious regiments. The Havoc was first publicly unveiled at the 2011 Gulf Defense and Aerospace exhibition in Kuwait.

   The Havoc is based upon the Finnish Patria AMV (Armored Modular Vehicle), and like the LAVs before, this vehicle is an 8x8 universal armored vehicle. It can be outfitted into a wide range of different configurations, with a myriad of combinations of subsystems, depending on the requirements of the customer.

   A wide range of weapons are compatible with the Havoc, the demonstrator vehicle was showcased with a 12.7 mm H2HB machine gun in an M101 Raven remote weapon system, and a 7.62 mm M240G auxiliary machine gun. No figures were available for the full ammo load-out of the Havoc in this configuration. Each of these weapons have a 100-round or 200-round capacity with standard ammunition belts and boxes.

   The accommodations for the Havoc are variable, due to the modularity of its design. The manufacturer claims that the base model has accommodations for up to 12 passengers and a crew of 2 are possible, though a production version would likely carry fewer men due to design growth and increased stowage. The interior volume of the base model is 12.3 m³.

   Propulsion is via a Scania DI 12 diesel engine with 540 hp, driving 8 wheels through a 5-speed automatic transmission. The engine can run on standard commercial diesel or JP-8 jet fuel, and with 540 hp propelling 17 tonnes, the base model has a power/weight ratio of 31.76 hp/tonne. Operating temperatures range from -30°C to +50°C.

   The Havoc is capable of a top speed of 105 km/h and a range of 900 km. It can tackle a 60% gradient, a 30% side slope, a 0.5 m vertical obstacle, and a 2.1 m trench. The turn radius is 12 m. With 17 tonnes atop 8 wheels, the Havoc thus has a ground pressure of approximately 2.28 kg/cm². It is fully amphibious without preparation, with a swim speed of 8-13 km/h. The manufacturer claims the Havoc can navigate ocean waters at up to Sea State 2, and inland water obstacles, without modification.

   A wide range of protection features are available for the Havoc, including blast protection up to STANAG 4569 level 4A and 4B. It withstands blasts equivalent to up to 9.5 kg of TNT under any wheel or anywhere under the hull. Ballistic protection is up to and above STANAG 4569 level 4 (14.5 mm armor-piercing rounds). The armor is composed of high-hardness steel, backed with spall liners. An overpressure NBC system is standard, and presumably, so is a fire & explosion suppression system. The wheels and tires have a run-flat capability, and the Havoc can move 50 km at 10 km/h on 8 flat tires. The Havoc has integral protection in its belly against threats up to a 9.5 kg anti-tank mine; rather than using a V-hull, as with most mine-protected vehicles, the Havoc employs a system referred to as a "subframe".

   The Havoc underwent full-scale testing for the MPC requirement in April of 2013, reportedly maintaining a 100% operational readiness rate throughout the tests. However the US Marine Corps cancelled the MPC requirement during the same year. In February 2014 the the MPC requirement was merged with the Amphibious Combat Vehicle (ACV) requirement, which called for a similar armored vehicle. However the Lockheed Martin's Havoc was eventually shortlisted. In 2018 a modified IVECO SuperAV, submitted by BAE Systems, was selected by the US Marine Corps to meet their ACV requirement. Production contract for initial batch of vehicles was issued during the same year.

   Eventually the Havoc received no production orders. The manufacturers have not released a figure for its unit cost. The future of the Havoc is uncertain as it was specially tailored for the USMC requirement and other countries might not require such a vehicle. There were no sub-variants of the Havoc, though the MPC and ACV projects required a command and repair/recovery variant as well as an APC.
