March 2026

Rating: Compared to financial year 24/25 Q4, the SRO Delivery Confidence Assessment (DCA) rating at 25/26 Q4 remained at Amber. This is primarily due to the following factors. 1. Delay caused by a combination of outstanding engineering design volume, supply chain performance, and COVID 19 related slowdown resulted in a schedule rebaseline to programme Initial Operating Capability, which was approved in early 2022 by the MOD Investment Approvals Committee and HM Treasury. 2. Importantly, quality has not been compromised, and T26 Frigates will be world class ships.

Schedule: Compared to financial year 24/25-Q4, the programme end-date at 25/26-Q4 remained the same at 01/05/2035.

Cost: Exempt under Section 43 - Commercial interests
