Talk:20-tube 7inch UP Rocket Launchers/@comment-2605:6001:F447:8400:3097:9809:1BCE:1676-20180730180717

You would be right in thinking that this is a piece of junk. It only got one or two 'claimed' kills and there were a lot of things that could go wrong with it due to the way it worked. Including the parachute mine it deployed floating back to the ship(s) that deployed it. Land based 3 inch version called the Z-battery probably would have worked better in concept but the proximity fuze was too new and would not fully mature until it reached the States. Like the Japanese launchers it had the same slow reloading problem.
