The #OMFV industry day last week provided some clarity and a few new angles on the requirement. A few highlights and thoughts below
(Image an old NGCV concept art, not from recent industry day)
Unsurprising desire to prioritise survivability, stated as #1 priority. At this stage specifics are unclear, but for contemporary ATGM/KE you need APS, ERA & some rather fancy composites. Even then overmatch will be tough in conjunction with mobility/transportability aspirations
Firepower requirements to engage infantry up to tanks, and helicopters. So an ATGM essential, and high elevation cannon. Given need for unmanend turret (see further down), could mean high profile turret, or loss of swept volume inside vehicle to allow that big 50 mm to elevate
The OM is back in OMFV. Clear statement that
"The OMFV should allow commanders to choose between manned or remote operation based on the tactical situation."
Not a small request, will be interesting seeing how contractors answer it. I note that it is 9th of 10 reqs for priority
"Each OMFV vehicle will be crewed by no more than two Soldiers who will be positioned in the hull. Squad members can perform crew duties prior to dismounting the OMFV but the vehicles must remain operational after dismounting."
So an unmanned turret and single commander/gunner
A few vignettes of notional OMFV company tasks moving from point of arrival to an attack and then defence against coutnerattack. Note the repeated referral to remote operation and survivability incl focus on hiding from enemt sensors
In terms of the distances involved in the above tasks, you're looking at up to around 375 km, maintaining pace with assumed accompanying M1 formations
Timelines broadly as we've seen before. Various development and testing with open competition through to FY27, then selection of a winner for LRIP in FY28/29 and FRP starting in FY30. So if all goes smoothly(!) then it will be 8 years from now to first deliveries, give or take.
Strong focus on a "modular open systems architecture" which whilst a rbaoder concept, always seems like a lot of effort not to use the term GVA. More on MOSA here dsp.dla.mil/Programs/MOSA/
OMFV remains one to watch as bidders assemble. Here's hoping its nth time the charm (depending how you look at it this is somewhere between 3rd & 7th go at a Bradley replacement now)
I remain firmly in support of this Doug Didia visioneering concept based purely on rule of cool

A few thoughts on belly loading. No, not our collective plans for the xmas period, a primer on the science behind allowing the belly of a vehicle to contact the terrain, and the implications therein to mobility (spoiler: its always bad) #AFVaDay#miltwitter#tanktwitter
Usual disclaimer - this is Twitter, I don’t have much space and so some things are simplified or omitted for simplicity. This is a hugely complex science; I’m just giving a flavour of the considerations inherent in AFV design. With that out the way…
Another outwardly unexciting concept, but actually quite critical to off road performance. Belly loading is the condition where the tracks have sunk in terrain to the extent that the belly of the vehicle is now partially or fully resting on the terrain
One of the more interesting angles on RCV for me is the classification of each type in terms of expected life, usage and risk of loss to enemy action
RCV-L is "attritable / disposable / expendable"
RCV-M "durable / attritable"
RCV-H "non-expendable / human survivability levels"
For reference, RCV-L programme being informed and requirements developed via the contract to QinetiQ and Pratt Miller for their bid vehicle, developed from the Pratt Miller Expeditionary Modular Autonomous Vehicle (EMAV).
RCV-M is using Textron Systems, Howe & Howe, and FLIR Systems Ripsaw M5 for their requriement. Again, not a small bit of kit to be in the semi-expendable / durable bracket. Broadly seems to mean
Having done mobility concepts to death of late, I thought it interesting to do a short thread on vehicle armour, specifically statistical armour (bar and mesh mainly) and tackling a few tropes around it. #miltwitter#tanktwitter#AFVaDay

What is bar armour? Also called slat/cage/mesh/net armour, its one of a range of methods collectively called statistical armour, so called as it presents a statistical likelihood of defeating a specific projectile type
A couple of years old, but a useful summary of some of the US Army's long range fires efforts, all oriented around radically extended reach for precision engagement of targets
Land Based Anti-Ship Missile (LBASM) repurposes the MGM-140 Army Tactical Missile System (ATACMS) to allow HIMARS and MLRS to engage ships. Not to be confused with the Navy's Long Range Anti-Ship Missile (LRASM). PrSM also being worked on as an option for the anti-ship role.
Single Multi-mission Attack Missile (SMAM) is a 35km range precision loitering munition. SMAM includes a self-contained launch tube and portable mast-mounted antenna. Total weight including the missile of 50-70lbs and controlled from a tablet relaying video feed
Part 7 of my Running Gear series, today looking at track types. The series is looking at all the bits of tracked vehicle mobility and started here (bit.ly/30596QZ) if you want to follow the threads. Hope its interesting.

Track comes in two flavours – single pin and double pin. Broadly speaking, double pin is the contemporary norm for most of the world, though there are plenty of single pin examples in service, especially in Russia where two pin is relatively new still
Part 6 of my Running Gear series, today looking at tracked suspension. The series is looking at all the bits of tracked vehicle mobility and started here (bit.ly/30596QZ) if you want to follow the threads. Hope its interesting.

Whilst there have been many historic suspension designs, contemporary AFV almost exclusively use either torsion bar or hydro pneumatic (hydrogas) systems, so I'm looking at those here. Historic stuff perhaps another day!
