Metropolitan Police Air Support Unit
The Air Support Unit (ASU) was a Central Operations branch of London's Metropolitan Police Service. The main responsibility of the unit was to provide aerial reconnaissance and other air support operations. Helicopters are particularly useful in aiding searches for missing persons, car pursuits, suspect capture and large public order operations such as football matches. The ASU also supported other emergency services, including the London Fire Brigade, London Ambulance Service and Marine Coastguard. On 31 March 2015 the National Police Air Service took over providing air support to the Metropolitan Police Service (along with all other police forces in England and Wales). This, in effect, resulted in the closure of the Metropolitan Police Air Support Unit.
The Metropolitan Police Service has also reportedly been secretly using Cessna aircraft for a number of years that have been fitted with surveillance equipment capable of intercepting mobile phone calls and listening in on conversations.
Formed in 1980, the unit was based at Lippitts Hill, Essex and had 48 personnel comprising 3 sergeants, 18 constables, 4 aircraft engineers, 1 avionics engineer, 11 pilots and was headed by an inspector. The unit also employed other members of staff, including operations room staff and an intelligence officer. The senior management were based at Wapping police station. All pilots were ex-military Royal Navy but also Army Air Corps. Each aircraft was crewed by a pilot with two officers acting as observers, and averaged over 260 flying hours per month.
In July 2007, the ASU took delivery of three new Eurocopter EC 145s costing a total of £15 million, using the call signs India 97, India 98 and India 99. Each aircraft has an L-3 Wescam MX-15 sensor pod which houses a gyro-stabilized color "day" camera and a thermal imaging camera with digital video downlink from the helicopter.
In 2012, after two years of training prior to the commencement of the 2012 Summer Olympics, the ASU added a new capability of officers being able to rope from helicopters becoming the first force in the UK with this capability after negotiations with the Department for Transport and other agencies.
In February 2015, it was announced that the control of the Metropolitan Police Air Support Unit was to be transferred to the National Police Air Service (NPAS) on 31 March, and that the base at Lippitts Hill would close in the following year. A projected new base at Elstree was intended to serve Hertfordshire, Bedfordshire, and Essex as well as London. However, by February 2017, a replacement for the Lippitts Hill base had not been procured, and the possibility of using RAF Northolt instead was being investigated.
On 7 September 2017 it was provisionally agreed by Epping Forest District Council to allow the unit to operate 3 helicopters and 1 fixed wing aircraft from North Weald Airfield in Essex, with a 25-year lease.
