The LAPCAT A2 is a design study for a 456 foot long hypersonic aircraft that could travel at speeds of mach 5, the design was designed by Reaction Engines Limited for LAPCAT, the aircraft aimed to use liquid hydrogen as its main fuel. because hydrogen needs a large footprint to hold enough for long range flights, the lapcats fuselage is very large, and only able to hold around ~300 passengers. Because the plane is hypersonic, the aircraft can travel to brussels (Belgium) to sydney (australia) in ~2-4 hours using the aircraft’s 4 Scimitar engines Boost MeThis is my 2nd model i have uploaded, if you enjoy it, consider giving a boost! I originally printed this model in October of 2025, and only now am i uploading it to here, the model needs assembly, the model when assembled is 34 cm long, if you enjoy this model, please leave a like and make sure to check out my 2nd account (@aplanelover2013) for single color models!! make sure to be careful when removing supports especially around landi
