UK Declared F-35 Operational Despite Issues, Auditors Say

Tony Osborne

The UK declared the F-35 operational even though the fleet was suffering from availability, infrastructure, logistics and security issues, auditors have revealed.

The UK National Audit Office (NAO) found that the December 2018 initial operating capability (IOC) from land bases was granted with 67 exceptions, with almost one-third of those still yet to be resolved more than a year later. It is not clear on how many criteria IOC (Land) was judged.

In its report studying how new capabilities are delivered into front-line operations, the NAO reported that in the run-up to the milestone there had been delays in the provision of synthetic training facilities. This impacted the availability of pilots and maintainers, while operational availability of the aircraft “hampered the ability to deliver training.”

The report appears to confirm the reasons behind a 34-day flying break by the UK-based fleet in the late summer of 2018 reported by Aerospace DAILY.

Plans to use simulators for training have been frustrated by “technical difficulties and delays in security vetting.”

The NAO said the UK Ministry of Defense is able to use exemptions when bringing a new capability into service. Capabilities that do not meet specifications but are deemed good enough would be given an exemption. The NAO also says that IOC acceptance criteria for the F-35 was not finalized “until several years” after business case approval in the second half of 2017.

Exemptions arose from “not being able to demonstrate deployability through a planned exercise,” because of aircraft availability, a reliance on contractors for mission support because of a lack of trained Royal Air Force personnel, and a lack of access to mission support training facilities in the U.S. Another challenge was an inability to program aircraft with UK mission data independently of the U.S. This has since been addressed with the opening of the Australian, Canadian and United Kingdom Reprogramming Laboratory (ACURL) at Eglin AFB, Florida, which was declared operational in February.

The NAO notes that some 20 of the exemptions had still not been resolved as of last month. But the NAO says the Royal Air Force and Royal Navy have made progress in the areas of training personnel and logistics.

The UK now has 15 F-35Bs based in the country flying with front-line unit 617 Sqdn. and with 207 Sqdn, a training unit. Since their arrival to the UK, the aircraft have been deployed to Cyprus and flown operational missions in the Middle East. They also recently took part in a Tier 1 Red Flag exercise with Five Eyes partners Australia and the U.S.

A Lockheed Martin spokesman said that while it was for the customer to answer questions concerning IOC, “the F-35 program globally continues to mature, and Lockheed Martin has made significant steps in terms of reliability and aircraft availability, with the global fleet averaging greater than 65% mission-capable rates and operational units consistently performing near 75%.”

Questions to the UK Ministry of Defense had not been answered at the time of publication.

    Future U.S. Navy Frigates Strengthened By Lockheed Martin Integration And Test Experience

    MOORESTOWN, N.J., July 19, 2019 – The U.S. Navy selected Lockheed Martin (NYSE: LMT) as the Combat System Ship Integration & Test agent for the Navy's future Guided Missile Frigate (FFG(X)) ship program. The Combat System Ship Integration & Test contract will ensure the overall integration of the combat system elements into the Frigate ship design and validate the installation through the completion of waterfront testing. The 10-year contract will consist of one base year and nine option years' worth up to $125 million. “The U.S. Navy will experience substantial efficiency by utilizing the existing processes, tools, and experience of the Lockheed Martin ship integration and test team,” said Chris Minster, Program Director, Lockheed Martin Surface Navy Integration Systems. “While minimizing ship impact and cost, our Ship Integration & Test team will enable the successful integration of the combat system elements into the future frigate ship design.” As the warfighter's needs change, Lockheed Martin has continuously evolved to quickly provide innovative and affordable capabilities to the fleet. Lockheed Martin has over 40 years of ship integration and test experience including Aegis Ticonderoga class guided missile cruisers and Arleigh Burke class guided missile destroyers. As the Navy's trusted Combat System Engineering Agent (CSEA), Lockheed Martin has successfully delivered and integrated Aegis and Aegis-based products on 126 platforms in eight nations, with an additional 23 under construction or planned. Aegis and Aegis-derived systems are in service in U.S. Navy cruisers, destroyers, Littoral Combat Ships, Coast Guard National Security Cutters and Aegis Ashore sites. The navies of Japan, Spain, Norway, the Republic of Korea, and Australia have also chosen Aegis to protect their nations.

    GA-ASI Plans to Demonstrate Maritime Capability in UK

    General Atomics Aeronautical Systems, Inc. (GA‑ASI) announces its plan to take a company-owned SkyGuardian Remotely Piloted Aircraft to the United Kingdom later this year to undertake a series of operational capability demonstrations for NATO allies, including the Netherlands. The UK's Protector program is a derivative of SkyGuardian with a range of UK modifications and the Royal Air Force (RAF) is supporting this visit. The GA-ASI aircraft will be configured with maritime capability, including a multi-mode maritime surface-search radar with Inverse Synthetic Aperture Radar imaging mode, an Automatic Identification System receiver, and a High-Definition, Full-Motion Video sensor equipped with optical and infrared cameras. This will build on previous GA-ASI demonstrations showcasing the unmanned advantage, which include the transatlantic flight of SkyGuardian in 2018, maritime demonstrations in Greece in 2019 and last year's validation flights in Japan. “GA-ASI will work closely with multiple European allies to demonstrate the capabilities of MQ-9B, including in the maritime environment, and how MQ-9B can complement and team within a networked environment with other national assets,” said Tommy Dunehew, vice president of International Strategic Development for GA-ASI. The series of civilian and military capability events is expected to kick off in July at the Royal Air Force's Waddington Air Base and will culminate with the MQ-9B's participation in the UK-led Joint Warrior exercise that will showcase how maritime capabilities can be integrated with other air, surface and land platforms. SkyGuardian flights will further develop GA-ASI's revolutionary Detect and Avoid capability, which will enable Protector to fly in unsegregated UK airspace. It will also assist RAF Waddington, the future home of the RAF Protector fleet, to best prepare to integrate the new aircraft into its daily operations. MQ-9B represents the next generation of RPA system having demonstrated airborne endurance of more than 40 hours, automatic takeoffs and landings under SATCOM-only control and the Detect and Avoid system. Its development is the result of a company-funded effort to deliver an RPA that can meet the stringent airworthiness certification requirements of various military and civil authorities. MQ-9B has garnered significant interest from customers throughout the world. The UK Ministry of Defence selected MQ-9B SkyGuardian for its Protector program, and in 2020 signed the production contract for deliveries to the Royal Air Force. SkyGuardian was selected by the Australian Defence Force under Project Air 7003, and the Belgian Ministry of Defense signed a contract for SkyGuardian. https://www.suasnews.com/2021/02/ga-asi-plans-to-demonstrate-maritime-capability-in-uk/
