EUROPEAN COMMON RADAR SYSTEM MK 2

Rating: Compared to financial year 24/25 Q4, the NISTA/SRO Delivery Confidence Assessment (DCA) rating at 25/26 Q4 remained at Amber. This is primarily due to the following factors. 1. The overall radar design schedule has stabilised and has successfully moved into the manufacture phase with confidence growing on production radars being available in 2028 as planned. However, securing an acceptable delivery schedule for P4E from Eurofighter through the NATO Eurofighter and Tornado Management Agency (NETMA), which is essential to embodying the radar, remains a significant challenge for the UK and Partner Nations. 2. Whilst P4E content has been agreed, Partner Nations are working continually with NETMA and Eurofighter to establish a progressive release of capability which meets each nation's operational need without being detrimental to delivery of the overall programme, alongside extensive transformation being pursued within the NETMA and Eurofighter enterprises.

Schedule: Compared to financial year 24/25-Q4, the programme's end-date at 25/26-Q4 remained the same at 01/08/2032.

Cost: Compared to financial year 24/25-Q4, the project's departmentally agreed Whole Life Cost at 25/26-Q4 (measured in £m) increased from £2902M to £2930M. This is primarily due to the following factors. 1. Minimal cost growth, principally down to increased Typhoon Defensive Aids Sub-System scope/requirements within P4E. 2. The Programme remains within its Approved Budgetary Level.

Rating: Compared to financial year 23/24-Q4, the Delivery Confidence Assessment rating at 24/25-Q4 remained at AMBER. This is primarily due to the following factors. FY 24/25 continued to present some key challenges. The important risk reduction activity of the ECRS Mk2 Step 1 (prototype system) flight trails have completed and the in-flight data will support the continued development of the system. Securing the UK Minimum Viable Product in the P4E has continued at pace with a plethora of challenging negotiations with Partner Nations. Some uncertainty has been addressed but significant challenges remain to assure the delivery of the ECRS Mk2 capability by 2030.

Schedule: Compared to financial year 23/24-Q4, the project's end-date at 24/25-Q4 remained at 01/08/2032. This is primarily due to the following factors. No change in project end-date.

Cost: Compared to financial year 23/24-Q4, the project's departmentally agreed Whole Life Cost at 24/25-Q4 (measured in £m) decreased from 2904 to 2902. This is primarily due to the following factors. Minimal change that remains within approval tolerances.

Rating: Compared to financial year 22/23-Q4, the Infrastructure and Project Authority's Delivery Confidence Assessment rating at 23/24-Q4 remained at Amber. This is primarily due to the following factors. Despite delayed completion of the System Critical Design Review from September 21 to November 23, closure of outstanding action is expected in April 24. This has not impacted on the critical path development activities towards the Initial Operating Capability which are centred around antenna development which is progressing in parallel. With the earlier placement of the Phase 1 contract with industry partners, allocation of sub-contracts with suppliers to secure long-lead and high value materials within the terms of the Instruction to Proceed is ongoing.

Schedule: Compared to financial year 22/23-Q4, the project's end-date at 23/24-Q4 increased from 2023-01-20 to 2032-08-01. This is primarily due to the following factors. The Q4 22/23 end date of 2023-01-20 was incorrect. It should have read 2032-08-01 and so is unchanged at Q4 23/24. Initial Operating Capability (IOC) and Full Operating Capability dates remain unchanged despite the delay to the System Critical Design Review. The establishment of a joint programme governance structure has allowed MOD and Industry to share information effectively and prioritise resources to maintain the schedule. The agreement of a proposal to complete radar development up to IOC has decreased the risk of schedule slippage in this area. Although progress has been made with the other Typhoon Partner Nations and their industries in fixing the scope and schedule of the development of the wider aircraft changes needed to integrate the radar and introduce other P4E capabilities, risk remains.

Cost: Compared to financial year 22/23-Q4, the project's departmental-agree Whole Life Cost at 23/24-Q4 increased from 2740m to 2904m. This is primarily due to the following factors. Reflects release of further budget to the Programme including the allocation of a budget for FY 32/33. The Programme’s Full Business Case was approved in March 2022 securing an Approved Budgetary Level (ABL) funding envelope which covers the equipment’s design and manufacture through to its Full Operating Capability and subsequent likely out of service date. There has been no change to the programmes requirements and the increase in Budgeted WLC is contained within the extant ABL.
