In order to speed replacement of the M109 mobile howitzers, some members of Congress had been pushing to speed up fielding of the M1203 NLOS-C 155mm mobile howitzer as a replacement for the USA’s aging M109s, even if this meant breaking Future Combat Systems’ unitary acquisition model by making NLOS-C a separate program. 
That didn’t happen, thanks in part to FCS critic Senator McCain’s [R-AZ] interesting intervention, but the message was clear.
That didn’t happen, thanks in part to FCS critic Senator McCain’s [R-AZ] interesting intervention, but the message was clear. The prototype of the Non-Line-Of-Sight Cannon, being developed as part of the US Army’s Future Combat Systems, fires its first 155mm round.
Unfortunately, even NLOS-C will break the C-130’s 20-ton cargo weight limit by a considerable margin (estimate: 27 tons, which works well in an Airbus A400M but not the C-130J Hercules). As such, FCS’ armored vehicle core is unlikely to ever deliver its most important touted benefit: deployability.
On the other hand, NLOS-C does offer new and fully modern mobile howitzers, an aim that has clear Congressional support. As such, the FCS program is making the NLOS-C the lead example for FCS’ tracked Manned Ground Vehicle (MGV) family.
This will be DID’s Spotlight article covering the NLOS-C sub-program, from its core platform and fit within Future Combat Systems, to its program and contracts, to additional research materials. The latest developments include the first firing of the NLOS-C while mounted on the MGV chassis.
