Cobham plc is a British manufacturing company based in Wimborne Minster, Dorset, England. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index. According to Defense News it is the 51st largest defense firm in world, and 5th largest in the UK, based on 2013 revenue.
Cobham was founded as Flight Refuelling Limited (FRL) at RAF Ford in Sussex by Sir Alan Cobham in 1934. It moved to Tarrant Rushton in Dorset in 1947. It became the first contractor to join the Berlin airlift in 1948 and developed the 'probe and drogue' method of air-to-air refuelling in 1949.
In early 2008 Cobham purchased S-TEC Corporation, maker of general aviation autopilots for $38 million, and in February 2008 Cobham bought the sensor and antenna systems division of BAE Systems for $240 million. Then in June 2008 Cobham acquired Sparta Inc., a US defence business, for $416 million (it was renamed Cobham Analytic Solutions). In September 2008 Cobham completed the purchase of the radio frequency components business of M/A-COM for $425 million.
In April 2009 Cobham agreed to purchase Argotek Inc., a provider of high-end information assurance services to the United States Intelligence Community, for $36 million. Then in June 2009 a Cobham – Northrop Grumman 50–50 joint venture won the US Army's US$2.4 billion competition to supply Vehicular Intercom Systems.
In October 2011 Cobham Analytic Solutions was sold for $350 million to the privately owned Parsons Corporation.
In June 2012 Cobham acquired Danish satellite communications company Thrane & Thrane A/S, making it the core of Cobham's new SATCOM strategic business unit (SBU), to include SeaTel marine, TracStar land and Omnipless airborne SATCOM product lines.
Cobham is organised into three technology divisions: Mission Systems, Defence Systems, Aerospace and Surveillance. The former Aviation Services division is now a strategic business unit (SBU) within Cobham Mission Systems.
The Cobham Mission Systems Division claims to be the world market leader in aerial refuelling, and provides a comprehensive range of weapons carriage and release equipment. Cobham Mission Systems also specialises in life support and personal survival equipment for aviators and astronauts.
The Cobham Aerospace and Security Division provides a range of electronic products for airborne, marine and land applications. Included in the product base are fully certified Electronic Flight Instrument Systems (EFIS), air and land Search and Rescue devices, and state of the art surveillance equipment.
The Cobham Aviation Services SBU operates more than 150 fixed and rotary wing aircraft around the world. It specialises in the conversion and support of a wide range of civil and military aircraft, and through an FB Heliservices consortium with Bristow Helicopters at the UK's Defence Helicopter Flying School trains all UK helicopter pilots for the Royal Navy, Royal Air Force and British Army.

The company produces the Guardian ST820, a battery-operated tracing device used by the American FBI. The device is secured under a car by a strong magnet. It is only available to law enforcement agencies. Due to these systems being clandestine, the company maintains a restricted access web site to discuss them.
