These are not modded parts, just working designs for bombs that will skid along the water surface. From left to right (first image) there is the smallest version which has an effective range of ~800yds when delivered from an altitude between 200 and 1400ft. The next one houses a boom 25 with the same effective altitude as the first and an effective range of ~700yds. The last one houses a boom 50 with an effective altitude of 200-1000ft and an effective range of ~500yds. All measurements were taken from being dropped from my A-10A which flies fully loaded at ~530mph. If you use these on your vehicle please send some credit my way or at least upvote this, thank you.
