Scientists at the US Naval Research Laboratory (NRL) have achieved significant progress in the ...

GE Aerospace and Lockheed Martin completed a series of engine tests demonstrating the viability of a liquid-fueled rotating detonation ramjet for use in hypersonic missiles, the first initiative ...

China has tested a powerful engine that can carry weapons at remarkable speeds through both air and water. The novel engine achieved 90% efficiency in laboratory tests, which were conducted in ...

A single shell now travels farther than traditional artillery ever could. Using a ramjet engine, this new 155mm round reaches ...

India recently announced that it had developed a 155mm Ramjet 155mm artillery shell. A ramjet is an air-breathing engine that requires no compressor or turbine because the high speed of the shell once ...

GE Aerospace and Lockheed Martin complete missile-scale rotating detonation ramjet tests, targeting longer-range and more efficient hypersonic weapons.

GE Aerospace is advancing hypersonic flight with plans to scale up its dual-mode ramjet technology in 2025. To create a full propulsion system, engineers will improve sophisticated controls and use ...

The development comes at a time when the army is looking at creating a rocket force at the earliest to boost its combat ...

Artillery has been for a very long time one of the best ways to fight the enemy from very far away. The ability to strike from a safe distance is a godsend for soldiers, as it gives them the ability ...

GE and Lockheed ground tested a new air-breathing hypersonic jet engine capable of powering missiles to speeds well in excess of Mach 5 in a smaller, cheaper, ...

In 1949 we saw the first aircraft, the Leduc 0.10, to fly entirely powered by a ramjet, which also directed compressed air into the engine – but this time compressed entirely by the aircraft's own ...

Engine maker GE Aerospace and defence manufacturer Lockheed Martin have teamed up to test a novel ramjet propulsion system for powering hypersonic flight. The pair say they completed a series of ...
