The FV1600 Truck, Armoured, 4x4, was better known as the Humber Pig. Developed in 1952, it entered service while Alvis Saracen 6x6 production ramped-up. Ideal for urban COIN ops, the Pig outlived Saracen with 1,700 produced. Every modern MRAP uses the same basic configuration. Image
The Humber Pig’s protection lags by today’s standards. But with a V hull and composite armour, it would offer similar protection to today’s Foxhound. The Humber Pig Mk 2 weighed 6 tonnes while Foxhound tips the scales at 7.5 tonnes. Image
The Thales Bushmaster is also very similar in concept to the Humber Pig. Like Foxhound, Bushmaster has a V hull, but is a larger vehicle, weighing around 15 tonnes. It can accommodate a full section of 10 soldiers. Image
Another (non-UK) 4x4 APC that deserves mention is France’s VAB. Entering service in the mid-1970s over 5,000 were built with a large number exported. Similar to Bushmaster in its ability to transport an entire section, VAB weighed around 14 tonnes. Image
All of these vehicles offer the same 5 benefits:
- Protected mobility for infantry
- Ability to self-deploy over long distances
- Lower cost relative to tracked equivalents
- Reliability & ease of support
- Flexibility to perform a wide range of other roles, e.g. C2, Ambulance.
The UK’s MRVP programme seeks to acquire a modern version of the Humber Pig. 10 years later, no vehicle had entered service. Foxhound fits the bill, but we have less than 400. Bushmaster is in service with SF, but we only have 24. @gduknews Eagle is available in 4x4 and 6x6. Image

THREAD ON AIRBORNE FORCES AND VEHICLES
Russia's failed attempt to seize Hostomel airfield in the early stages of its invasion of Ukraine provides confirmation (if any was needed after the lessons of Crete and Arnhem) that airborne assaults against well defended targets can be disastrous. The contemporary use of drones only adds to the risks.Image
This means that future airborne operations will primarily be conducted at battalion and company level for coup de main missions against bridges, airfields, and objectives that need to be physically seized and held by forces on the ground. Think WW2 Pegasus Bridge. Many previous airborne tasks, especially raiding tasks, can now be accomplished using PrSM, loitering missions, or armed drones, so demolition roles will be the exception rather than the norm.Image
Airborne missions at brigade level are likely to be risky, particularly for the large fleet of aircraft and helicopters required to deliver them. Where larger formations are needed, they will be used to occupy locations where there are no or limited enemy forces. In this respect, airborne units will become early entry forces rather than assaulting in contact with the enemy.Image

The cancellation of the US Army's M10 Booker has little to do with the quality of the vehicle itself, and more about the lack of supporting infrastructure of Infantry Brigade Combat Teams, which cannot effectively support 40-tonne tracked vehicles. 1/4 Image
In the same way that the British Army's Ajax programme includes six different versions, so that armoured cavalry regiments are self-supporting, the Booker chassis lends itself to a whole range of variants based on the M10 Booker Repair & Recovery variant. 2/4 Image
In case Ajax's issues still aren't fully resolved, migrating each variant to the M10 Booker chassis would be a certain fix for Ajax, Ares, Athena, Argus, Apollo, and Atlas. You'd have to compromise on the original requirements, but you'd have an excellent vehicle. 3/4 Image

It was right to retire the British Army's Thales Watchkeeper WK450 UAS. It took far too long to bring it into service and by the time it arrived, newer and better systems were available. It was also difficult to operate. The question is what do we replace it with? (1/6) Image
An obvious choice is General Atomics Mojave, which is optimised for STOL operations from austere locations. This has a larger payload, double the range and better ISR sensors. It can also carry up to 16 Hellfire missiles for strike tasks. Crucially, it is harder to jam. (2/6) Image
Mojave, which is a modified version of General Atomics' MQ-1C Gray Eagle UAS, weighs 1½ tonnes and has a reinforced undercarriage. Technically, it compares well to Watchkeeper while also being considerably less expensive to purchase and operate. (3/6) Image

The @GD_LandSystems M10 Booker is not a derivative of the ASCOD platform, but an all-new design. The hull has well-sloped armour, an 800 hp diesel driveline and @Horstman_Group hydro-pneumatic struts. The 105 mm gun based on the UK ROF L7 and is mounted in an Abrams-based turret. Image
As impressive as the vehicle itself is the acquisition approach. 12 prototypes from two companies were down-selected. These were tested extensively. A winner was chosen and awarded a LRIP contract for 26. Now that all issues are resolved a full production contract can be issued.
At each stage of the process, risk was managed. The onus was on @GD_LandSystems to resolve any issues in order to move the program to the next stage. Brigadier Glenn Dean, who has assumed overall responsibility for MPF deserves credit for doing a fantastic job.

Over the last 15 months, @LockheedMartin's M270 & HIMARS rocket launchers have performed extremely well, obliterating Russian targets while reducing collateral damage at ranges of 70 km, which is beyond the enemy's capacity to return effective counter-battery fire. ImageImage
Ukraine's success with HIMARS confirms what we already believed, that precision-guided deep fires rockets and missiles enable smaller armies to deliver an effect that belies their size relative to larger, less capable adversaries. Image
Before the Russo-Ukrainian War, the USA had already initiated an upgrade programme to increase GMLRS range from 70 km to 150 km, while the new Precision Strike Missile (PrSM) can hit targets at 499 km, versus the existing ATACMS with a 150 km range. This is a significant upgrade. Image

The British Army's Protected Mobility Pipeline (PMP) programme will see 14 platforms merged into 5. Three PM platforms (light, medium, & heavy) will replace Foxhound, Mastiff, Ridgeback, Wolfhound, Husky, Foxhound, and Panther. This will streamline through-life support. Image
As good as Boxer is, only 4 infantry battalions will be equipped with it. So having a larger fleet of lower cost PMVs will be essential. Also, the way in which they're being used in Ukraine, as battlefield taxis that move infantry out-of-contact, points to a new way of operating. Image
For some roles, it makes sense to purchase an off-the-shelf solution from abroad (e.g., Oshkosh JLTV) where the price is lower than domestically produced vehicles can match. But for others, British industry is perfectly capable of producing a state-of-the-art 4x4 or 6x6 PMV. Image
