We are getting better and better at killing each other. Pure luck if you survive a modern war.
The XM1155 round is compatible with all 155 mm artillery
Raytheon Missiles & Defense is developing a ramjet-propelled shell that will double the range of US military artillery to over 100 km (62 mi). Working under a US$7.9 million US Army contract, the tactical 155mm XM1155 Extended-Range Artillery Projectile is designed to combine increased range with precision targeting technology.
One example of this is the XM1155 project, which aims at creating an artillery round that doesn’t just fly ballistically but incorporates a ramjet to propel it and extend its range. Though the details of how the new round will work have yet to be divulged, the principle of the ramjet means that the gun would fire the round, accelerating it to a fast enough speed to compress the incoming air inside the ramjet’s combustion chamber to allow it to ignite and run.
