[4][6] The RAF operates a number of Voyagers which are militarised multi-role tanker transport (MRTT) aircraft; ZZ336 Vespina is a specific Voyager KC3 aircraft painted in a 'Global Britain' livery, and fitted with secure satellite communications system, missile detection, fifty-eight business-class seats (front cabin), one hundred 'premium economy' standard seats (rear cabin),[7] and media facilities, similar to other dedicated air transports of heads of state and government.

This new paint scheme was designed with the assistance of Airbus, and was carried out by Marshall Aerospace and Defence at its facilities at Cambridge Airport,[4] and returned to RAF Brize Norton on 25 June 2020.

[3][18] The main aim of the new colour scheme is to "promote the UK around the world while transporting Ministers, senior members of the Royal Family and their delegations on trade, diplomatic and other missions".

[9] In 2021, Charles and Camilla (then Prince of Wales and Duchess of Cornwall) flew in Vespina to Jordan as part of their Royal Tour; the aircraft was powered by a blend of Sustainable Aviation Fuel (SAF).

[25] Vespina also participates in state military guard of honour flypasts in the United Kingdom,[26][27] notably the 2022 Trooping the Colour which formed part of the celebrations of the Platinum Jubilee of Elizabeth II,[28] and sometimes forms the lead part of a formation along with the Royal Air Force Aerobatic Team, commonly known as the Red Arrows,[29] a role most notably previously undertaken by a Concorde of British Airways.

As with the rest of the UK Voyager fleet, ZZ336 Vespina is made available to commercial operators for revenue-earning air charter flights under the terms of its contract with AirTanker Services Limited.
