Huge Explosive Bullets Destroying Boats!

Naval Surface Warfare Center dal green laboratory is performing a cost and operational effectiveness analysis from the 20 millimetres surface mode CIWS the stabilized weapons platform system SW PS a hybrid 25 millimeter gun and missile system and the advanced minor calibre gun system the analysis was requested by the Deputy Assistant Secretary of the Navy for shifts the center recently conducted lethality test supporting the AMC GS program and the cost and operational effectiveness analysis two types of target boats were configured as hostile attack boats one was a 65 foot aluminum mark three patrol boat with a quarter inch thick all it was outfitted with 50 caliber machine guns fore and aft and a 6 pod launcher containing 24 5 in Zuni rockets the 1/8 inch thick aluminum pilot and deck house structures housed a nerd ammunition and equipment the boat had a crew of five each wore protective army Kevlar flak jackets and m1 steel helmets the five man crew consisted of a pilot a navigator two 50 caliber gunners and a radio operator the other targets were 36 foot and 32 foot fiberglass boats the 36 foot target boat had a 1 foot thick fiberglass foam sandwich construction hoe the 32 foot boat had a 1/4 inch thick fiberglass hull each had a four-man crew which included a pilot a navigator and 50 caliber gunners fore and aft the 36 foot fiberglass target was destroyed by fire initiated by a 30 millimeter hei round impacting on the pilot house on the second day of testing testing continued using the 32-foot target vote for the firing tests each boat was positioned at 1500 meters with a bow aspect of 15 degrees to the firing position and then at 3,000 meters with a broadside aspect three types of 25 millimeter ammunition were fired from a game twist seven point five degree exit angle Gow 12 man barrel the Navy marked 210 high-explosive incendiary tracer or hei T round with an M 505 point detonating fuse the army M 792 hei T round with an M 758 point detonating self-destruct fuse and the army M 793 target practice tracer round four types of 30 millimeter ammunition were fired from a game twist seven degree exit angle modified gau-8 man barrel the PG u13 hei round with an M 505 point detonating fuse the PG u13 hei with an M 758 point detonating self-destruct fuse an experimental semi armor-piercing hei or Safi round and the PG u 15 target practice round the M 505 fuse is a simple inexpensive tri-service fuse used on twenty twenty-five and thirty millimeter rounds previous history with the 20 millimeter m56 hei round has shown the consistent m 505 fuse function is dependent upon projectile mass impact velocity and angle of impact the US Army M 758 point detonating self-destruct fuse was used on both the 25 millimeter M 792 and 30 millimeter PG u 13 rounds the M 758 fuse consistently initiated a high order warhead detonation on impact two for two for alpha one for one Romeo one oh three one Delta three one Delta firing tests were conducted from March 10th to May 5th 1992 the objective was to compare the lethality of the 25 millimeter in 30 millimeter rounds by firing both calibers at the same targets and then assessing the amount of damage caused here are some of the representative testify you you analysis of test results indicates that of the 1725 millimeter mark 210 h EIT rounds fired at the mark 3 petrol boat anchored at 3000 metres 7 rounds hit the target of these three penetrated and detonated on the eighth inch thick aluminum pilot house three rounds hit the 1/4 inch thick hull and detonated without penetration and one round impact of the hull without penetration or definition of 53 30 millimeter hei rounds fired at the mark 3 patrol boat anchored at 3000 metres 20 rounds impacted detonated and penetrated the hull and pilot house and one round hit and detonated on the hull but could not penetrate because of the ribs support reinforcement of the hull plate at both 1,500 and 3,000 metres the 30 millimeter hei rounds caused nine times more hole area damage and five times more internal forward volume damage than the 25 millimeter hei t realms you
