SC Group. SC Group is a British manufacturer of military vehicles and related equipment. It was known as Supacat Ltd until 2015. Supacat was established in 1981 and based at Dunkeswell Aerodrome in England. SC Group now comprises four companies: Supacat, SC Innovation, Proteum and Blackhill Engineering.

SC Group initially specialised in the design and development of military and civil high mobility vehicles. Throughout the last decade the company expanded its portfolio considerably to encompass developing equipment for operation in harsh environments in sectors including marine, renewables, mineral exploration, oil & gas and nuclear power. During 2014, the then Supacat made a series of acquisitions in the commercial marine sector leading to the creation of the now Proteum based in Hamble, UK.  At the end of 2014 Exeter-based heavy fabrication specialist, Blackhill Engineering, was acquired.

The current CEO is Nick Ames who joined the company in 2003. Nick Jones, original co-founder of Supacat, remains a Director of SC Group.

Supacat
The Supacat brand is retained by SC Group for the group's core defence business. Supacat develops and supports high mobility military vehicles and provides specialist engineering services for defence customers. It is a member of Rheinmetall's Challenger 2 Life Extension Project (C2 LEP) team.

All Terrain Mobility Platform
The All Terrain Mobility Platform (ATMP) is a 6x6 marginal terrain vehicle now in its fourth generation. Around 200 ATMPs have been supplied to mainly military users since 1982, including the armed forces of Canada, Malaysia, Mexico and the UK.

High Mobility Transporter

The High Mobility Transporter (HMT) vehicle platform is produced in three variants the HMT 400 (4x4), the HMT 600 (6x6) and the HMT Extenda (configurable between 4x4 and 6x6). A HMT 800 (8x8) variant is also available. The HMT was designed in mid-1999 by HMT Supacat Limited later renamed to HMT Vehicles Limited. In 2004, Lockheed Martin entered into a licence agreement with HMT Vehicles Ltd to manufacture and sell the HMT in North America. In 2006, Lockheed Martin (UK) acquired HMT Vehicles Ltd who licensed the design back to Supacat.

The HMT 400, the first of the platform to enter service, was developed for the United Kingdom Special Forces procured under Project Minacity to replace the Land Rover 110 Desert Patrol Vehicle. A contract was awarded in 2001 for 65 vehicles that entered service in 2003–2004 in Afghanistan following tenders in the late 1990s. In 2004, the U.S. Army Delta Force purchased 47 similarly configured vehicles designated Marauders which were delivered in 2004–2005.

In 2006, Danish Army Hunter Corps ordered 15 HMT Extenda vehicles. In 2007, the Australian Army Special Air Service Regiment ordered 31 HMT Extenda vehicles known as Nary designated as the Special Operations Vehicle-Special Reconnaissance (SOV-SR) which due to technical problems did not enter service until 2011.

In 2014, the Australian Army 2nd Commando Regiment ordered 89 HMT Extenda MK2 vehicles known as the Special Operations Vehicle-Commando (SOV-Cdo) that will be reconfigurable in four configurations. In 2015, the Norwegian Army Forsvarets Spesialkommando ordered an undisclosed number of HMT Extenda vehicles to be delivered from 2017 to 2019. In 2016, the New Zealand Special Air Service ordered an undisclosed number of HMT Extenda vehicles designated as the Special Operations Vehicles – Mobility Heavy (SOV-MH) to be delivered from late 2017.

The British Army is the biggest user of the HMT with purchases between June 2007 and late 2010 of the HMT 400 designated as the Jackal and HMT 600 designated as the Coyote totalling 575 vehicles.

The British Army has also developed specialist variants of the HMT. Two projects, named Project Soothsayer and the Lightweight Mobile Artillery Weapon System Gun (LIMAWS(G)) were cancelled in 2007. Supacat's HMT 600 is the chosen ground station platform for the UK MoD's Watchkeeper unmanned air vehicle (UAV) project.

Failed bids
  Canada: A bid was submitted by Supacat to the Canadian Special Operations Forces Command to replace their High Mobility Multipurpose Wheeled Vehicle (HMMWV). In 2010, the Project was cancelled, after the HMT was the only vehicle that was bid, and it was determined that it did not meet all of CANSOFCOM requirements.

Proteum

Proteum is the marine brand within SC Group and was formed following the acquisition of MDS Marine and Bukh Diesel UK.

Proteum  represents and distributes a portfolio of marine products and services across the UK and Ireland, these including Bukh, Marine Diesel Sweden, OXE Diesel and Konrad propulsion systems.  The company has two UK offices, these in Poole and Hamble.

At the DSEI 2015 defence and security exhibition held in London, 15–18 September, OXE Diesel launched what the company claims to be the first viable high power NATO single fuel policy compliant diesel outboard engine for military users.  According to the company, the 200 hp outboard has the highest power density of any marine diesel and incorporates a self-contained belt propulsor unit (S-BPU) to eliminate bevel gears and transfer shafts. In addition, the unit uses a conventional automotive engine block adapted for marine use, and unlike most outboards is mounted horizontally to improve reliability and reduce maintenance.

Blackhill Engineering Services

Blackhill Engineering Services is a heavy fabrication and machining specialist. Supacat Limited acquired Blackhill in late 2014.

Blackhill Engineering Services Ltd. has existed in various forms since the 1950s; originally its main role was to provide an engineering centre for English China Clays (Quarries Division), which looked after capital and revenue repairs, modifications, projects and servicing, for sites all over the United Kingdom and Channel Islands. Early in 1995 the company became privately owned.

Production of SC Group's SC Innovation's Lifeboat Launch and Recovery System (L&RS) is now undertaken by Blackhill Engineering.

In October 2015 Blackhill Engineering issued a press release informing it had been contracted by Supacat, also part of SC Group, to manufacture replacement chassis frames for the Supacat Jackal vehicle.
