A Team Tempest industry team brings together the expertise of national defence champion BAE Systems and propulsion house Rolls-Royce, along with the UK arms of Leonardo and MBDA. Working with the Ministry of Defence (MoD) and the Royal Air Force (RAF) Rapid Capabilities Office, their collective ambition is to deliver a new manned fighter, along with unmanned systems – operating as a so-called “additive capability” – and increasingly sophisticated and networked air-launched weapons.
Seems to me to still be planned as a manned fighter, but with a "loyal wingman" type unmanned aircraft system networked to operate alongside.
