The Airbus Helicopters EC135 / H135 is a lightweight five/seven seat twin-turbine-engine multi-role helicopter with a radius of 720 km. The EC135 is offered with either Safran Helicopter Engines (former: Turbomeca) Arrius 2B2 or Pratt & Whitney PW206B2 engines. Development of the Eurocopter EC135 started in the 80s as the MBB Bo.108 Advanced Technology Helicopter. The prototype BO108 with conventional tail rotor flew first on 15 October 1988. When the helicopter divisions of MBB from Germany and Aérospatiale from France merged in January 1992 to form the Eurocopter Group, the Bo108 program was transferred as well. An advanced low noise ducted 10-blade Fenestron tail rotor was, next to other modifications, incorporated into the design and the name of the helicopter was changed into Eurocopter EC135. The prototype of the EC135 (D-HBOX s/n S-01) flew first on 15 February 1994 and went in series production in 1996 at Donauwörth. On 14 June 1996, the German certification was granted by the LBA and the first customer delivery followed on 31 July that year. Next to the EC135 a special military version was developed designated the Eurocopter EC635. The EC635 has a structural reinforcement of cabin structure and can be equipped with wire-guided, laser-guided, autonomous missiles. Over 1300 EC135 / H135 / H135M airframes have been delivered since the helicopter entered service in 1996. In March 2015, Airbus Helicopters renamed its entire product line to better reflect its closer allignment with ist parent company and simplify the naming convention for the portfolio. Therefore, the EC135 T3/P3 were renamed as “H135” as stated in revison No.EASA.R.009 Issue: 07 of the Type Certificate Data Sheet for EC135 dated 18 March 2015. “H135M” is used as marketing designation for the military EC635 P3(CPDS); EC635 P3H; EC635 T3(CPDS) and EC635 T3H helicopters. The ICAO Aircraft Type Designator for the EC135 / H135 helicopters is EC35.

As a result of the merger between the Eurocopter parents Aérospatiale-Matra; DaimlerChrysler Aerospace (DASA) and Construcciones Aeronàuticas Sociedad Anonima (CASA) in July 2000, the Eurocopter group became a division of the new formed EADS (European Aeronautic Defence and Space company). Taking off into 2014, EADS was rebranded as "Airbus Group". Uniting all its activities under a single brand, its helicopter division Eurocopter was rebranded as Airbus Helicopters on 8 January 2014.

On 4 February 2002, Eurocopter Deutschland was permitted to fly the Eurocopter EC135 T1 s/n 0215. On 15 April 2002, the EC135 T1 was registered G-XMII in the UK with McAlpine Helicopters Ltd., Kidlington. On 4 November 2002, the G-XMII was registered with Merseyside Police Authority, Merseyside Police Air Support Group, Liverpool, the territorial police force responsible for policing Merseyside in North West England. In 2004, the helicopter returned to McAlpine Helicopters for an upgrade to the EC135 T2 standard. In service with Merseyside Police Air Support Group the helicopter was known as X-Ray Mike 11. On 22 May 2012, registration G-XMII was cancelled as exported to Norway. On 23 May 2012, the EC135 T2 was registered LN-OCB with Merseyside Police Authority, Liverpool, as owner and Oslo Politidistrikt, Politiest Helikoptertjeneste Oslo Politidistrict, Oslo, as operator. On 10 April 2015, the ownership of the LN-OCB changed to Police and Crime Commissioner for West Yorkshire, Wakefield. The Norwegian Police leased the Eurocopter EC135 T2 as replacement for the time that Eurocopter EC135 T2 LN-OCP 'Helifalcon 01' would undergo maintenance. The lease should be for four years from 1 June 2012. On 31 May 2016 it was expected to revert to the UK where it should once again be an NPAS (National Police Air Support) spare aircraft. Just like Eurocopter EC135 T2 LN-OCP the LN-OCB is based at Oslo-Gardermoen Airport.
