Significant milestone as Spear 3 cruise missile set to be test-fired by end of this year

Spear 3, the UK's next-generation air-launched surface attack weapon, is due to reach a major milestone with its first guided firing scheduled for later this year.

Defence Procurement Minister Maria Eagle made the announcement in response to a written question from Conservative MP James Cartlidge about the programme's future funding plans.

She said: "The Spear 3 programme is currently in the demonstration phase.

"The next significant milestone is the first guided firing, scheduled to take place later this year.

"Total investment in the Spear 3 programme comprises approximately £1.4bn."

The first guided firing of the Select Precision Effects At Range (Spear) Capability 3, had initially been set for 2022, but was delayed for technical reasons.

The weapon will be used to provide air-to-surface capabilities and is set to be central to the UK's future air combat strategy.

Spear 3 had been due to be operational by 2025, although the missile's full operating capacity on the F-35B might not now be achieved until 2028.

The missile system should be capable of operating across a wide range of platforms, including the Eurofighter Typhoon, F-35B Lightning and potentially the future Tempest aircraft.

Spear, which has a range of more than 140 kilometres, is notable for its compact size, weighing under 90kg and measuring 1.8 metres in length.
