There isn't much information out there at all about the X51 helmets, which were developed and tested during the 1950s. They were seen as an attempt to use new technology to improve upon the M1 helmet, which had served the U. S. Military well during WWII. Also with the post war budget cuts, they looked to create a "Universal Helmet", which would be able to meet the needs of all service members.
