Government completes 26 major projects that deliver policy priorities and improve public services

https://www.gov.uk/government/news/gove ... c-services
Annex A: Explanation of DCA ratings

The Delivery Confidence Assessment (DCA) is the IPA’s evaluation of a project’s likelihood of achieving its aims and objectives, and doing so on time and on budget.

Green

Successful delivery of the project on time, budget and quality appears highly likely and there are no major outstanding issues that at this stage appear to threaten delivery significantly.

Amber/Green

Successful delivery appears probable; however, constant attention will be needed to ensure risks do not materialise into major issues threatening delivery.

Amber

Successful delivery appears feasible but significant issues already exist, requiring management attention. These appear resolvable at this stage and, if addressed promptly, should not present a cost/schedule overrun.

Amber/Red

Successful delivery of the project is in doubt, with major risks or issues apparent in a number of key areas. Urgent action is needed to address these problems and/or assess whether resolution is feasible.

Red

Successful delivery of the project appears to be unachievable. There are major issues with project definition, schedule, budget, quality and/or benefits delivery, which at this stage do not appear to be manageable or resolvable. The project may need re-scoping and/or its overall viability reassessed.

Reset

A significant change to a project’s baseline which involves a business case refresh or change.

IPA Delivery Confidence Assessment
(A Delivery Confidence Assessment of the project at a fixed point in time, using a five-point scale, Red – Amber/Red – Amber – Amber/Green – Green; definitions in the MPA Annual Report)
  • Amber/Red
Description/Aims
  • The Lighting Programme will deliver a true multi-role, carrier-capable strike asset to be operated jointly by the RAF and RN, which will provide the UK with a survivable, sustainable, expeditionary, 5th Generation air capability to contribute to the widest possible range of operations.
Departmental commentary on actions planned or taken on the IPA RAG rating.
  • Delivery confidence within the Lightning Programme remains AMBER/RED following a downgrade by the SRO in the last quarter to reflect the significant challenges that exist within a taut schedule. Following significant cross-party effort, progress has been made around UK weapons integration to deliver Initial Operating Capability (IOC). Similarly, although representative simulator training remains as a key risk, the OEM are proposing mitigations which will provide the necessary training to our pilots. Further pressure remains in our Operational Test area, where there is a continued need to ensure that our Test teams have appropriate early access to capabilities; together with DE&S DT Lead, the Team continues to successfully progress these issues with US authorities. The continued uplift of DE&S personnel into the DT is very positive, and, whilst it will take some time to ensure they are fully trained and familiar with this complex programme, will offer enhanced capacity and strategic depth for the UK F-35 enterprise.

Project - End Date
(Latest approved end date)
  • 31.03.2035
Departmental narrative on schedule, including any deviation from planned schedule (if necessary)
  • The schedule for the UK F-35 Programme is taut, but remains on track to deliver UK IOC by Dec 2018, and also remains on track to deliver IOC-Maritime and Full Operating Capability.
2017/18 TOTAL Baseline £m
(including Non-Government costs)
  • £ 935,45
2017/18 TOTAL Forecast £m
(including Non-Government costs)
  • £ 903,35
2017/2018 Variance %age
  • -3,43150355443905%
Whole Life Cost TOTAL Baseline £m
(including Non-Government costs)
  • £ 10109,38
Departmental narrative on budget/forecast variance for 2017/18
(if variance is more than 5%)
  • Despite exchange rate adjustments now being delegated down for absorption in the Programme, the variance in budget remains within tolerence at less than 5%.
Departmental Narrative on Budgeted Whole Life Costs
  • The forecast whole life costs continue to deliver the following:

    a. Production of main phase of approved a/c buy due to be completed in 2024 (Includes Aircraft and Equipment procurement).

    b. Through life capability development and obsolescence management.

    c. Delivery of unique sovereignty capabilities.

    d. UK contribution to production, sustainment & follow-on development.

    e. UK development & integration (including Ship, Weapons and Main Operating Base).

    f. UK participation in Initial Operational Test & Evaluation

    g. Through-life programme sustainment

    h. DIO Infrastructure.

    As the Programme moves through LRIPs, URF costs continue to see a reduction in line with the Cost Learner Curve.

the first inert GBU-12 (test) bombs were dropped from F-35Bs aboard the HMS Queen Elizabeth off the east coast, demonstrating warfighting capability and an opportunity to gather important test data. This marked the first time American-made bombs have ever been embarked on a UK ship.

Contrary to reports, all F-35 jets have not been grounded.

We have paused some F-35 flying as a precautionary measure while we consider the findings of an ongoing enquiry.

Flight trials from HMS Queen Elizabeth continue and the programme remains on schedule.

Test Milestone Achieved! Check out the video of an F-35B conducting the first Shipborne Rolling Vertical Landing (SRVL) aboard the aircraft carrier HMS Queen Elizabeth. On 13 October, an F-35B touched down traveling approximately 40 knots and decelerated to a standstill in 175 feet. The SRVL enables warfighters to recover to the ship with more stores.

Supersonic speeds could cause big problems for the F-35′s stealth coating (12. Juni 2019)
At extremely high altitudes, the U.S. Navy and Marine Corps’ versions of the F-35 jet can only fly at supersonic speeds for short bursts of time before there is a risk of structural damage and loss of stealth capability, a problem that may make it impossible for the Navy’s F-35C to conduct supersonic intercepts.

The Defense Department does not intend to field a fix for the problem, which influences not only the F-35’s airframe and the low-observable coating that keeps it stealthy, but also the myriad antennas located on the back of the plane that are currently vulnerable to damage, according to documents exclusively obtained by Defense News.

The F-35 Joint Program Office has classified the issues for the "B" and "C" models as separate category 1 deficiencies, indicating in one document that the problem presents a challenge to accomplishing one of the key missions of the fighter jet. In this scale, category 1 represents the most serious type of deficiency.

Both deficiencies were first observed in late 2011 following flutter tests where the F-35B and F-35C both flew at speeds of Mach 1.3 and Mach 1.4. During a post-flight inspection in November 2011, it was discovered the F-35B sustained “bubbling [and] blistering” of the stealth coating on both the right and left sides of the horizontal tail and the tail boom.

During similar tests of the F-35C in December 2011, “thermal damage” that compromised the structural integrity of the inboard horizontal tail and tail boom were apparent.

Vice Adm. Mat Winter, who leads the F-35 program on behalf of the Pentagon, told Defense News that the department has taken steps to mitigate the problem with an improved spray-on coating, but added that the government will not completely fix it — instead accepting additional risk.

As justification for the decision, Winter noted that the issue was documented while the jet was flying at the very edge of its flight envelope. He also said the phenomenon only occurred once for both the B and C models, despite numerous attempts to replicate the conditions that caused the problem.

“How often do we expect something like that to occur?” he said. “It's very, very small.”

Greg Ulmer, Lockheed Martin’s F-35 program head, said there have been no cases of this problem occurring in the operational fleet and that incidents have been limited to the “highest extremes of flight testing conditions that are unlikely replicated in operational scenarios.”
