The second ship fitted with Sea Ceptor has also conducted a successful firing to verify the weapon system upgrade, said UK Ministry of Defence.
The first firings of Sea Ceptor were conducted from HMS Argyll at the Hebrides range off the coast of Scotland and involved firing the system to assess its performance against a range of scenarios.
Two sets of trials were conducted by Defence, Equipment and Support (DE&S) and supported by a number of other organisations, lasting around two weeks each.

During the firings the system was first tested against single aerial targets. This was followed by more demanding tests, including a single target engaged by two missiles and a twin firing (two targets, each engaged by a single missile at the same time).

An installation test firing from HMS Westminster – the second ship fitted with Sea Ceptor – took place in November, with each of the Type 23 ships due to carry out installation test firings in due course.
The new missile defence system will provide UK personnel with a powerful shield against airborne targets – including hostile combat jets and helicopters, as well enemy missiles travelling at supersonic speeds.
The completion of the firing trials from Type 23 frigate HMS Argyll means Sea Ceptor can proceed to the next stage of the acceptance into service with the Royal Navy.
