Stryker Howitzer Test-Firing

Todd at Stryker Brigade News contacted me with more news on the recent test-firings of the LAV-3-based 105mm howitzer. (Mentioned here and here.)


According to DefenseLink, which I had seen but don’t have access to,

The cannon was designed for indirect fire at ranges between 4 kilometers
and 30 kilometers at a rate of eight shots per minute.

It can fire six types of ballistically compatible rounds, including a
bispectral smoke round, visual and infrared illumination rounds, a practice
round, a regular high-explosive round and a highly lethal pre-form fragment
(PFF) round.

The PFF technology, traditionally used in anti-missile weapons, has
“migrated” to 105mm ammunition to increase the lethality of the artillery,
Gyfford Fitchat, Denel executive manager of business development in the
United States, said during a cannon demonstration here April 16.

The PFF rounds contain 7,800 tungsten balls, which when fired “pretty much
wipes out a soccer field,” Jim Vickrey, director of artillery programs at
General Dynamics Land Systems, said at the same demonstration. “This is not
your father’s 105.”

  1. Interesting. When I first heard of the Howitzer on the Stryker, I envision a turning turret. But seeing that Stryker itself can be turn rather easily, that feature isn’t necessary. Since the firing is along the long axis of the vehicle, balacing isn’t as difficult as if the gun is turn (which it can’t).

  2. BigFire: Actually, the howitzer IS mounted in a turret. It appears that the turret itself consists of canvas, at this point of development, but the gun can be traversed and fired to the sides. Apparently, the recoil isn’t much of a problem like on the Stryker MGS, but we’ll see.

  3. The turret is solid, not canvas. Not sure what that picture is showing, but I assure you that the turret is complete.

  4. USTanker: I checked out the pics I was looking at again, and you are totally correct. The turret is solid, though it is painted a slightly different color than the hull. Not really sure why I thought it might just be a mock-up. Thanks for the catch.

  5. Canada is looking into these. Your picture shows a collaboration with South Africa’s Denel called the Leo-105. Another collaboration with BAE Systems has produced the V2C2 system, also mounted on a LAV-III (Stryker). BAE Systems has also put together the 155mm M777 ultra-lightweight howitzer with a tracked chassis to create an NLOS-C mockup for the Future combat Systems. The US, Britain, and Canada are all fielding the M777 in its towed version.
