“marauder2048” included a link to this DOD Ordnance Technology Consortium web page in a comment on my earlier post, “Remember the ALaMO,” noting a contract to conduct a “Demonstration Against Unmanned Aerial Systems (UAS) Targets” using the 57mm ALaMO round. But looking through the web site there were some other contract awards that I found interesting, including indications the 50mm program is still progressing. The list includes contracts for both FY 2020 and FY2021.
The following 50mm contracts, totaling $64.39M, were awarded to ATK (Northrop Grumman) in FY2020.
- Aug. 2020, 1904 INIT 4096 B, 50 x 228mm High Explosive Airburst, Traced (HEAB-T) Munitions, $44.30 M
- Sept. 2020, project 1904 INIT 4104 B, 50 x 228mm Target Practice Munitions, $20.09 M
The following 50mm contracts were awarded to GD-OTS, General Dynamics Ordnance and Tactical Systems, in FY2021:
- Oct. 2020, project 1904 INIT 4051 B, 50x228mm Programmable Airburst Ammunition – EMD, $46.42 M
- Oct. 2020, project 1904 INIT 4052 B, 50x228mm Target Practice Munitions – EMD, $17.62 M
- March 2021, 1904 INIT 4050, XM1203 50mm x 228 Armor Piercing Fin Stabilized Discarding Sabot with Trace (APFSDS-T) Cartridge Engineering and Manufacturing Development (EMD), $25.20 M
There are some interesting awards in other categories as well. There are these contracts for 30mm systems that do not appear related to the 30mm Mk46 currently in the USN inventory. These sales, late in FY2020, could be for foreign military sales:
- Sept. 2020, project 1905 INIT 5046 B, MSI-DS Mk113 30mm Naval Gun Weapon System, to MSI-Defence Systems US Inc, for $11.14 M
- Sept. 2020, 1905 INIT 5249 B, New Deck Mounted, Stabilized 30mm GunMount, to BAE Systems, for $11.66 M
Then there is this:
- Apr. 2020, 101 INIT 0865, Counter Unmanned Aerial System (CUAS) 40mm Proximity Sensor, Electronics Development Corporation (EDC), $4,628,000
This is apparently in reference to the 40mm Mk19 Grenade machine gun, which is, I believe, on the PATFORSWA Webber class WPCs. This could mean it is to be used as a hard kill system against small Unmanned Air Systems, though the Mk19, with its very low muzzle velocity, seems a strange choice for an anti-air weapon.
