On September 28, 2018 an F-35B Lightning II jump jet piloted by Cmdr. Nathan Gray hovered down for a landing on the HMS Queen Elizabeth off the coast of Maryland—the first fighter to land on a Royal Navy carrier in eight years. It was followed by another F-35B piloted by a Royal Air Force pilot.
Over the next eleven weeks, the UK and the United States will fly two F-35B test airframes pilots to perform 500 more takeoffs and landings on the carrier. The Queen Elizabeth is expected to enter routine operational service in 2020 or 2021.
Just over a century ago the Royal Navy deployed the first ever aircraft carrier with a flight deck from which aircraft could takeoff and land, and in 1918 dispatched six Sopwith Camels on the first carrier-based air strike in history, targeting the zeppelin base at Tondern. In subsequent decades, the Royal Navy carriers played a critical role projecting British sea power—particularly during the 1981 Falklands War .
But the budgetary crunch of the Great Recession led the Royal Navy to prematurely retire all three of its Invincible-class carriers (two in 2010, the third in 2014) as well as the Harrier GR9 jump jets that flew off them—leaving the world’s once preeminent sea power without any carriers with operational fighters.
Launched in 2014, the Queen Elizabeth was the first of two huge new replacements grossing three time the weight of the preceding Invincible-class at 71,600 tons. In 2017 she was joined by the Prince of Wales , which narrowly avoided cancelation. The new class is distinguished by having two islands (raised superstructures) on the starboard side of the 280-meter long deck—the forward for ship navigation, the aft for flight control. But until this September, the new carriers didn’t have jets to fly off them.
The QE-class carriers are the largest warship ever built by the UK In fact, they are the largest actively serving anywhere in the world today save for two big exceptions: the Nimitz and Gerald Ford-class nuclear-powered carriers of the U.S. Navy. While the American supercarriers retain significant advantages over their British brethren, they come at an important price: the new Gerald Ford-class will cost between $10 to $14 billion each, while the two QE vessels together cost the equivalent of $8 billion. The QE carriers have a crew complement of 679 personnel plus up to 1,000 in the carrier air wing—less than third of the personnel required for a U.S. carrier.
Nuclear propulsion provides near limitless range and allow high sustained cruising speeds of thirty knots, which among other benefits, allows a carrier to outpace diesel-electric submarines, which rarely much exceed twenty knots. However, nuclear propulsion would have added billions to construction and operating costs of the British carrier. Instead, they employ two gas turbines and four diesels to generate 110 megawatts to power ship systems and impel its propellers. The QE vessels are only slightly slower at twenty-five knots—and some reports suggest they may even exceed thirty. While the British vessels will require refueling with a range of 10,000 nautical miles, a nuclear carrier’s unlimited range is also constrained by the need to replenish aviation fuel .
However, a carrier’s value comes ultimately comes from the aircraft it carries. UK defense planners had to choose between furnishing the new carrier with jump jets like the Harriers deployed on the Invincible-class, or installing a Catapult-Assisted Take Off and Barrier Assisted Recovery (CATOBAR) system to launch higher-performance fighters carrying heavier weapon and fuel loads.
The UK was a major partner to the American F-35 program, and conveniently the stealth fighter came in both the F-35B jump jet model and the F-35C CATOBAR-takeoff variant. Originally, the Royal Navy intended to configure one carrier for each type. However, after calculating that a CATOBAR carrier would cost an extra $2 billion, the defense ministry stuck with the jump jets.
Though the F-35B has shorter maximum range or payload than other variants, it’s still a far superior fighter compared to the Harrier. The Lightning’s stealthy radar cross sections allows it to penetrate deep into enemy airspace before being detected on radar by opposing fighters or surface-to-air missile batteries. Despite being a bit slower than most fourth-generation fighters with a top speed of Mach 1.6, the F-35 is a lot faster than the Harrier’s subsonic Mach 0.86 to 0.95. British F-35Bs are also configured to employ ASRAAMs, a short-range heat-seeking missile which outranges its peers by 25 to 50 percent.
The F-35Bs usually perform a short-distance takeoff using a ski jump ramp on the end of the QE’s flight deck—it’s when they return for landing that they switch to vertical lift mod. There’s a fly in the jump jet ointment, however—the 1,500 degrees centigrade temperatures generated by the exhaust threaten to damage the carrier decks. Operational tempo will be restricted until special heat-resistant paint is applied.
