Answer the following question: Information:  - MBDA is a European developer and manufacturer of missiles. It was formed by a merger of French Aérospatiale-Matra Missiles (of EADS, now Airbus Group), Italian Alenia Marconi Systems (now Leonardo) and British Matra BAe Dynamics (of BAE Systems) in December 2001. In 2015 the company had 10,000 employees. In 2015, MBDA recorded orders for €5.2bn and an order book of €15.1 bn. MBDA works with over 90 armed forces worldwide.  - Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the object(s). Radio waves (pulsed or continuous) from the transmitter reflect off the object and return to the receiver, giving information about the object's location and speed. Radar was developed secretly for military use by several nations in the period before and during World War II. The term "RADAR" was coined in 1940 by the United States Navy as an acronym for RAdio Detection And Ranging or RAdio Direction And Ranging. The term "radar" has since entered English and other languages as a common noun, losing all capitalization.  - British Aerospace Dynamics Limited (BADL or BAe Dynamics) was a division of British Aerospace.  - Alenia Marconi Systems (AMS) was a major European integrated defence electronics company and an equal shares joint venture between BAE Systems and Finmeccanica until its dissolution on May 3, 2005.  - The Battle of Britain (German: "die Luftschlacht um England", literally "Air battle for England") was a combat of the Second World War, when the Royal Air Force (RAF) defended the United Kingdom (UK) against the German Air Force (Luftwaffe) attacks from the end of June 1940. It is described as the first major campaign fought entirely by air forces. The British officially recognise its duration as from 10 July until 31 October 1940 that overlaps with the period of large-scale night attacks known as the Blitz, while German historians do not accept this subdivision and regard it as a campaign lasting from July 1940 to June 1941.  - Active radar homing (ARH) is a missile guidance method in which a missile contains a radar transceiver (in contrast to semi-active radar homing, which uses only a receiver) and the electronics necessary for it to find and track its target autonomously. NATO brevity code for an air-to-air active radar homing missile launch is Fox Three.  - Brimstone is an air - launched ground attack missile developed by MBDA for Britain 's Royal Air Force . It was originally intended for `` fire - and - forget '' use against mass formations of enemy armour , using a millimetric wave ( mmW ) active radar homing seeker to ensure accuracy even against moving targets . Experience in Afghanistan led to the addition of laser guidance in the dual - mode Brimstone missile , allowing a `` spotter '' to pick out specific targets when friendly forces or civilians were in the area . The tandem shaped charge warhead is much more effective against modern tanks than older similar weapons such as the AGM - 65G Maverick , while the small blast area minimises collateral damage . Three Brimstones are carried on a launcher that occupies a single weapon station , allowing a single aircraft to carry many missiles . After a protracted development programme , single - mode or `` millimetric '' Brimstone entered service with RAF Tornado aircraft in 2005 , and the dual - mode variant in 2008 . The latter has been extensively used in Afghanistan and Libya . An improved Brimstone 2 was expected to enter service in October 2012 , but problems with the new warhead from TDW and the ROXEL rocket motor put back the planned date to November 2015 . MBDA is working on the targeting of swarms of small boats under the name Sea Spear . The RAF intend to fit Brimstone to their Eurofighter Typhoons , and planned to integrate it with their Harriers until they were withdrawn from service in 2010 . MBDA is studying the use of Brimstone on ships , attack helicopters , UAVs , and from surface launchers ; it will be integrated on the Lockheed Martin F - 35 Lightning II when the F - 35B enters British service . The United States , France and India have expressed interest in buying Brimstone for their aircraft , but Saudi Arabia is the only export customer as of 2015.The cost per missile has been quoted as £ 175,000 ( $ 263,000 ) each in 2015 , or ' over £ 100,000 ' .  - BAE Systems plc is a British multinational defence, security and aerospace company. Its headquarters are in London in the United Kingdom and it has operations worldwide. It is among the world's largest defence companies; it was ranked as the third-largest based on applicable 2015 revenues. Its largest operations are in the United Kingdom and United States, where its BAE Systems Inc. subsidiary is one of the six largest suppliers to the US Department of Defense. Other major markets include Australia, India and Saudi Arabia. The company was formed on 30 November 1999 by the £7.7 billion merger of two British companies: Marconi Electronic Systems (MES)  the defence electronics and naval shipbuilding subsidiary of the General Electric Company plc (GEC)  and British Aerospace (BAe)  an aircraft, munitions and naval systems manufacturer.  - The Royal Air Force (RAF) is the United Kingdom's aerial warfare force. Formed towards the end of the First World War on 1 April 1918, it is the oldest independent air force in the world. Following victory over the Central Powers in 1918 the RAF emerged as, at the time, the largest air force in the world. Since its formation, the RAF has taken a significant role in British military history, in particular, playing a large part in the Second World War where it fought its most famous campaign, the Battle of Britain.  - Matra BAe Dynamics was formed in August 1996 by merger of half the missile business of Matra Defense of France and BAe Dynamics (a division of British Aerospace) of the UK and was Europe's largest manufacturer of missiles and UAVs.
