Panzermann Posted December 11, 2015 Share Posted December 11, 2015 Nice. Is the SMG120 Rak-G mounted on a modified 2S1 hull? Link to comment Share on other sites More sharing options...
Damian Posted December 11, 2015 Author Share Posted December 11, 2015 Yes, however bare in mind it's only temporary solution. The final vehicle will be based on BWP Borsuk chassis, our new IFV currently also in development by HSW, the developer of artillery systems. BWP Borsuk early concept images from HSW. As for 120mm Rak mortar system, the turret is autonomous module that can be placed on wheeled, tracked chassis, or on naval vessel, and even on stationary post.

EchoFiveMike Posted December 12, 2015 Share Posted December 12, 2015 I'm not so sure that the trade off of bigger bang on target and faster RoF of 120mm mortar is worth losing the range and low angle trajectory of 122mm howitzer. Does(did) Poland have indigenous production of 122mm guns? Was there some other reason for the switch? S/F.....Ken M Link to comment Share on other sites More sharing options...

Damian Posted December 12, 2015 Author Share Posted December 12, 2015 (edited) Nobody says 122mm SPH 2S1 will be completely phased out. As for 120mm SMK120/SMG120 Rak mortars, they can fire both in direct and indirect fire modes. And yes, HSW had a full license to manufacture 2S1 howitzers. Just recently HSW also started building a new guns manufacturing line, in future that line will be capable to manufacture not only artillery pieces but also for example tank guns.

Damian Posted December 12, 2015 Author Share Posted December 12, 2015 No, turret is designed completely in Poland, 100% domestic product. Link to comment Share on other sites More sharing options...

Reminds me of a brochure from Patria some years ago, that had drawings of the AMOS turret on any hull that could not get away fast enough. On CV90, MT-LB, BMD, M113 and some more hulls iirc. btw, is this a rifled or smooth bore mortar? Link to comment Share on other sites More sharing options...
Panzermann Posted December 12, 2015 Share Posted December 12, 2015 is the 120mm turret a BAE design? It looks very similar to a design that was knocking around 15 years ago for a 120mm turret that could fit on Warrior and M113.The number of different looks for a single tube turreted mortar is a bit limited. The AMS has a different barrel assembly: http://defense-update.com/products/a/amsII.htm Link to comment Share on other sites More sharing options...
Damian Posted December 12, 2015 Author Share Posted December 12, 2015 btw, is this a rifled or smooth bore mortar? Yes. Im impressed, it looks very neat. Yep, additional feature of 120mm automatic mortar Rak, is that it can be remotely controlled, both in case if the turret module is mounted on vehicle, or on the stationary post. You can actually see this at one of videos showing it during tests, where all operations are realized through remote control. Link to comment Share on other sites More sharing options...

DB Posted December 12, 2015 Share Posted December 12, 2015 Looking at the Krab wikipedia page, it notes that three different guns have been used so far - the "original" AS90 one, a Nexter one and now a Rheinmetall. this seems a bit odd. Any enlightenment available? Link to comment Share on other sites More sharing options...
Damian Posted December 12, 2015 Author Share Posted December 12, 2015 (edited) Yeah, just change in manufacturers over time. Only two original prototypes used Royal Ordnance gun, later first test production batch used Nexter ones, then production switched to Rhinemetall, but final production will be in Poland, when HSW complete their new gun production facility. Remember that due to politican and economic problems, AHS Krab program was nearly cancelled, and was in limbo for nearly over 10 years!

Damian Posted December 12, 2015 Author Share Posted December 12, 2015 (edited) Oh sorry, my fault, yes it is a smoothbore as far as I know. At least looking down the barrel I do not see any rifling. Edited December 12, 2015 by Damian Link to comment Share on other sites More sharing options...

The USMC 120mm rifled M327, aka French R2M shoots 120mm fin stab rounds just fine. Makes it handy when raiding US Army ASP's.

Panzermann Posted December 12, 2015 Share Posted December 12, 2015 Okay. Noted. How does it do that? is it oversized and the smooth bore grenade rides on the lands? And how is accuracy compared to a smoothbore? Link to comment Share on other sites More sharing options...
EchoFiveMike Posted December 13, 2015 Share Posted December 13, 2015 Beats me, but you can plainly see it works. I'd bet it simply rides the rifling and seals with the obturator band on the shell. S/F.....Ken M Link to comment Share on other sites More sharing options...
