How CSG21 deployment proved UK’s reborn carrier strike credentials

  1. >After more than a decade without fixed-wing maritime aviation on the front line, the Royal Navy (RN) and Royal Air Force (RAF) are close to completing the first operational outing for the UK’s new “fifth-generation” carrier strike capability.

    >Led by the 65,000t aircraft carrier and fleet flagship HMS Queen Elizabeth, the six-and-a-half month CSG21 deployment to the Indo-Pacific region has taken a multinational force halfway round the world, by way of the Atlantic, Mediterranean, Suez and the Indian Ocean.

    >It has also provided an important test for the two squadrons of Lockheed Martin F-35B Lightning II combat aircraft embarked, including live combat missions against Daesh, intercepting Russian jets over the eastern Mediterranean, and major multi-carrier exercises in the Pacific, Philippine Sea, and Bay of Bengal.

    >“Carrier strike gives the UK a brand new capability for which the Royal Navy unashamedly has the lead on,” says Rear Admiral Martin Connell, director force generation in Navy Command Headquarters. “While from the outside that might appear to be relatively straightforward, it is a significant change for us.

    >“It marks the end of a challenging decade, at the beginning of which we retired the old Invincible-class carriers and the [BAE Systems] Harriers that served us so well. At the same time, we were doubling down on a new carrier capability, and we as the navy had to learn and understand what that meant. That forced us to look really closely at what it was we would want to develop from a sovereign UK perspective.”

    >REGENERATING POWERS

    >Rebuilding and regenerating carrier capability has demanded that the RN and RAF put old enmities to one side. It has also hinged on the assistance provided by key allies, acknowledges Connell.

    >“The French have been a part of that, yes, but particularly the US Navy and the US Marine Corps [USMC]. The extent to which our partners across the Atlantic have helped us on this journey has been incredible,” he says.

    >Reflecting the strength of this relationship, Queen Elizabeth’s air group for CSG21 has included 10 F-35Bs from the Marine Fighter Attack Squadron 211 (VMFA-211) alongside eight jets from the RAF’s 617 Sqn.

    >While the initial move to bring a USMC squadron on board stemmed primarily from the slow ramp-up of the UK’s own Lightning Force, it has at the same time given the RN and the RAF a golden opportunity to demonstrate what levels of interoperability and interchangeability can be achieved with their US partners.

    >“VMFA-211 has not just embarked as an element of tokenism,” Connell emphasises. “It’s a front line, combat-ready US Marine Corps F-35 squadron fully integrated with the strike group. And we’ve been testing the bounds of that day in, day out. Their energy and focus, and the fact that they’re a couple of years ahead of us with the aircraft, has undoubtedly helped us.”

    >While interoperability – typically sharing a common tactical picture with allies and partners – is standard practice for the RN, interchangeability goes a step further.

    >“Having one nation’s aircraft, munitions and people being carried on another nation’s warship reflects the level of trust that exists between the US and the UK,” Connell says. “It’s not easy, and in the last few years we’ve worked really hard on this.”

    >Embedding VMFA-211 in Queen Elizabeth’s air wing demanded detailed understanding of operating procedures, the provision of special access compartments on board, and clearances for embarked munitions and specialised equipment – such as the Raytheon Joint Precision Approach and Landing System. A USMC colonel is integrated into the strike group staff as US senior national representative.

    >“In going down that route we’ve realised that you are no longer bound by your own force structure,” Connell says. “We now know that, with very little effort, a Marine Corps F-35 squadron can embark in either of our carriers at relatively short notice.”

    >Commander UK Carrier Strike Group Commodore Steve Moorhouse and his staff have led the CSG21 deployment from Queen Elizabeth. Speaking in early November as the strike group was heading for a short logistics stop in Duqm, Oman, he told FlightGlobal that high-tempo operations in the Eastern Mediterranean had tested the mettle of the air wing early on in the deployment.

    >“Back in late June, we were supporting, with F-35, ships from the task group that had pushed up into the Black Sea and were working with RAF [Eurofighter] Typhoons already based in Romania. So that was already a complex air and maritime space where we haven’t previously put fifth-gen jets.

    >“Concurrently, other elements of the air wing were flying east into Iraq to support Operation Shader. That was a busy time, and as the carrier moved further east, it was increasingly apparent we were attracting the attention of the Russian forces that are based in Syria.

    >“So we were also having to maintain a ready alert on the deck to counter daily probing from the Russian air force coming out to the carrier. Over 30 live intercepts of armed Russian fighter and bomber aircraft were conducted in just over two weeks.

    >“Responding to quick alert like that is something the Royal Navy hasn’t done with aircraft carriers for a generation. So that’s meant understanding the readiness state that you have to maintain so you can get the jets off at sufficient time to ensure you can intercept an incoming aircraft at appropriate range.”

    >This intensive period of flying operations served to build confidence and accelerate proficiency ahead of the transit through Suez, and subsequent eastward passage into the Indo-Pacific.

    >By late July, as units from the Chinese People’s Liberation Army Navy were shadowing CSG21 through the South China Sea, the force was demonstrating its ‘blue water’ credentials. Units and air wings undertook both day and night flying; a number of anti-submarine/anti-surface warfare activities were completed; and flight operations were conducted from Queen Elizabeth concurrent with replenishment at sea operations.

    >“We were flying fixed-wing almost continuously through the 24-hour period, which is something the US doesn’t do – they surge for 15-hour, maybe 18-hour periods, whereas we were able to keep flying over 24 hours, fixed and rotary-wing,” says Moorhouse. “It really allowed us to show the unique flexibility and agility of Queen Elizabeth-class aviation.

    >“For example, flying fixed-wing while replenishing is really quite straightforward for us once you’ve got everyone trained and good to go. And we don’t need much wind [over the deck] to launch the jets, even at full weights in hot conditions.

    >“We are clearly different to an American CVN [nuclear-powered carrier],” he adds. “We don’t have catapults and arrestor gear, we’re not in the same scale in terms of air wing size, and the F-35B does not have the same legs.

    >“But [Queen Elizabeth] offers something completely different in its agility to get aircraft up and off. A CVN is incredibly impressive, but it is operated very differently and simply does not have the same flexibility.”

    >Another first, completed in August during exercises in the Pacific, saw Queen Elizabeth demonstrate F-35 cross-deck interoperability with the amphibious carrier USS America. “We had VMFA-211 F-35s launch, fly several hundred miles, land on America, take on fuel, and load weapons,” says Moorhouse. “Having launched to drop weapons on a range, they recovered to America for another suck of gas before returning to Queen Elizabeth.

    >“We do that routinely with helicopters, but to do that with a jet is a real first,” he says. “And it really excited the [US] because they could start to see for themselves how they would use F-35B in that region as part of their wider campaign plans for distributed maritime operations.”

  2. >Notwithstanding the challenges and constraints imposed by Covid-19, and the loss of a UK F-35B during operations in the Mediterranean on 17 November, CSG21 has largely hit or exceeded its marks.

    Exceeded its marks at a loss of 10% of its strike force. How many fighters did they expect to lose?
