The two-year extension encompasses 30 Merlin Mk2 maritime patrol helicopters and 24 Mk4/Mk4A amphibious lift aircraft.
The partnership focused on evaluating AEUK's autonomous navigation system using BMT’s proprietary SEAS testbed.
It was previously unconfirmed which class of warship the under-development UK air defence laser would be installed upon.
The trials are aimed at assessing and verifying the ship's capabilities at sea, with delivery scheduled for 2025.
