Recently, Boeing has won a US $30 million contract from the weapons division of the U.S. Navy Air Combat center to develop the supersonic ramjet mission demonstrator. Spear flight demonstration will be used to help determine the technical requirements for future missile defense naval vessels. < / P > < p > just as the balance of power between countries is always changing, so are the threats and responses faced by the Navy. The typical example is the aircraft carrier, these huge floating airports are almost the symbol of the powerful power and status of the 21st world. It can operate on a global scale, providing both a means to project power and immediate and substantial assistance in the event of a natural disaster. < / P > < p > the problem is that although aircraft carriers are very powerful military weapons, they are also very vulnerable. That’s why frigates are needed for every carrier trip. Without protection, a modern fighter can deal a very serious blow to an aircraft carrier. For this reason, the original intention of the US Navy to promote the spear (the supersonic propulsion enabled advanced ramjet), hoping to be more lethal to fighters and able to resist threats without exposing itself to unnecessary danger. The supersonic ramjet missile is not new. They have been deployed since the 1940s, but striking solid fuel ramjet missiles such as the MBDA meteor that fighters can carry is a relatively new development. < / P > < p > for the new contract, Boeing and the Navy will produce a spear demonstration in the second half of 2022, which will provide the technical information required for practical shipborne land-based and maritime strike weapon systems.
