Olin Corp.’s Winchester Division in East Alton, IL received $43.4 million indefinite-delivery/ indefinite-quantity with firm-fixed-price orders for .50 calibre M903 saboted light armor penetrator (SLAP) and M962 saboted light armor penetrator tracer (SLAPT) bulk and the 4 ball (M903) to 1 tracer (M962) configuration.
The .50 caliber SLAP ammunition was developed by the US military during the mid/late 1980s for the M2 heavy machine gun, known as “Ma Deuce.” It uses a reduced caliber, heavy metal (tungsten) .30 inch diameter penetrator wrapped in a plastic sabot or “shoe” of .50 inch diameter.
The SLAP ammo is much lighter in weight than the normal ball .50 caliber ammunition, so its velocity can be significantly increased in an unmodified M2 heavy machine gun. This produces a fast round with a flat trajectory which enhances hit probability. The SLAP ammo has a velocity of 3,985 feet per second and a maximum effective range of 4,921.5 feet.
Olin will perform the work in East Alton, IL (50%), Towanda, PA (26%), Jonesborough, TN (8%), Independence, MO (6%), Hopkins, MN (4%), Wood Dale, IL (4%), St. Marks, FL (2%) with an estimated completion date of June 30/16. For the order, 1 sole source bid was solicited with 1 bid received by the Joint Munitions & Lethality Contracting Center at the Picatinny Arsenal, NJ (W15QKN-10-D-0010).
