The jet measures 15.6 metres (51.2ft) in overall length, has a wingspan of 10.7 metres (35ft) and a height of 4.36 metres (14.3ft).
Its top speed comes in at 1.6 Mach or 1,200 mph, that's 1.6 times the speed of sound.
The jets will have a maximum thrust tops 40,000lbs, an amazing range of 900 nautical miles and a combat radius of 833km.
The Lightning has a max G rating of 7G which can be compared to the g-force felt in Apollo 16 on re-entry to Earth (7.19g).
Unlike earlier generation fighter jets, the Lightning II will carry its weaponry internally, decreasing the drag and its radar signature.
Depending on missions, the typical armament on the F-35B's includes a 25mm cannon, two bays for air missiles, a further two for bombs up to 450kg. Two wingtip mounds for air to air missiles and four for air to surface or ground missiles.
The jet itself is made by many different companies. The main contractor is Lockheed Martin, with BAE systems making around 15 pieces of each airframe and Rolls-Royce making the lift fan.
The F-135-600 engine has been built by Pratt & Whitney.
The Lightning will provide the 5th Generation carrier-strike capabilities to the Royal Navy’s two new carriers - HMS Queen Elizabeth and HMS Prince of Wales.
Rather than the traditional catapult launch, the F-35B will take off from HMS Queen Elizabeth via the ski jump ramp.
The jet is capable of two types of landing - vertically onto the deck, and also through the shipborne rolling vertical landing, which using forward airspeed, allows the aircraft to bring back several thousand pounds of extra weight to the ship.
HMS Queen Elizabeth itself weighs 65,000 tonnes and has a top speed of 25 knots.
Its flight deck is 280 metres long and 70 metres wide, enough space for three football pitches.
In 2015, a test pilot revealed that during a dogfight, the advanced jet was unable to manoeuvre and shoot down a 40-year-old F-16 jet. Coincidentally one of the jets the F35B II is destined to replace.
