GDLS isn't going to win because their lobbyists are better, they didn't have to "redo" the Stryker and the issues with the Ajax (made by GDUK) are irrelevant.

 

Come on Ram, the current Stryker DVH shares basically zero parts with Stryker as originally delivered. The suspension was modified several times and eventually outright replaced, the hull has been modified to the extent of very limited parts compatibility, the powerpack was entirely replaced...

 

The "regular" stryker to DVH conversion involves taking existing hulls, stripping them basically to the hull itself, modifying the hull to the new spec - and then bolting on the new 6.0 running gear, installing the new powerpack, and all that jazz.  If that's not a "redo" of the thing, than I don't know what is. Virtually nothing is left from the vehicle as originally ordered and designed.

 

Furthermore, while yes GDUK is doing the work on Ajax - it was the GD global leadership who decided to make the proposal based on ASCOD 2 and the existing ASCOD 2 Spanish supply chain, which is what has caused all of the Ajax's issues; it's not poor work at GDUK that is the problem. There's even statements in the parliamentary questioning that GD as a whole has been spending money sent to them as part of the Ajax program on the global ASCOD 2 portfolio.

The current A1 Stryker is also a 20 year newer vehicle without the requirement restraints of the original. Lincoln axe'ing old vehicles to keep them up to date is common. Look at how little of the original Abrams or M109 remain, is the SEPv3 a "redo" of the M1?

Have either Austria or Spain encountered the issues the British have with their vehicles?

Dean said the source-selection phase of the competition is ongoing and the program is on schedule for a production decision in the third quarter of fiscal 2022 — around June. The plan is to equip the first unit with MPF by the fourth quarter of FY25.

The Army plans to initially build 26 vehicles, with an option to build 28 more and retrofit eight prototypes.

Well no, but Austria and Spain only operate ASCOD Gen 1s (until Castor enters service in Spain) - which were entirely designed by Steyr before GDLS took them over. It's a very solid, if conventional late cold war IFV.

 

But ASCOD 2 is a near-clean sheet design, and not only has Ajax been a mess but so has VCZAP Castor - the new engineering vehicle the Spanish are buying based on ASCOD 2. Castor is the project parliamentary questions brought up GDLS (as a whole) had used money on that was disbursed as part of the Ajax payments. The track record with ASCOD 2 for both clients deep into the contracts for them (UK's Ajax family and Spain's Castor) have been a complete mess.

 

Meanwhile, the Sabrah LT for the Philippines on ASCOD 2 chassis has also slipped a few months. It was supposed to be December '21 first deliveries, but now it's "2022" (which we are a quarter through almost) for them. They aren't even full up ASCOD 2s, but just the chassis with turret and outfitting by Elbit. Something stinks at ASCOD 2 land.

An issue in this discussion is the fact, that there is not clean definition of "ASCOD 2". The name was already used by Steyr-Daimler-Puch Spezialfahrzeug to distinguish between the Pizarro (ASCOD 1) and the Ulan (ASCOD 2). Later it was used for the ASCOD 35 in comparison to the Pizarro and Ulan. At the same time the Pizarro Fase 2 has been described as ASCOD 2 (specifically by British journalists saying that the Ajax was based on the Pizarro Fase 2), despite being much closer related to the Ulan than the ASCOD 35.

What's the fuel capacity of the Stryker DVH ?

 

Flat bottom Styker only had 200 L.

Flat bottom Stryker had 53 gallons fuel capacity, which is roughly 200 litres. On Stryker DVH this was increased to 63 gallons (238 litres).

 

For the sake of comparison: the Boxer has fuel tanks for 530 litres, VBCI has 420 litres fuel capacity, Patria AMV (Rosomak) has 325 litres capacity and Piranha IIIH of the Swiss Army has 320 litres fuel tank capacity.

This is a fair point, all of my use of "ASCOD 2" is for the ASCOD 35 development. I get the feeling the Journalists calling Pizarro P2 ASCOD 2 is just simple mistakes, as Pizarro P2 is literally Ulan but with Spanish fittings and a domestic transmission (SG850).

Not very pleasing to look at. The driver has no hatch/vision blocks? There are no headlights? I hope that is a very, very early mock-up.

Army is all about cameras these days. I wouldn’t be surprised if periscopes become a thing of the past. No need for headlamps with thermal cameras. Headlights are never used in combat anyways. Looks like it has reflection lights integrated in the hull.
