(back to topic) the version of sm-6 each country procures (or is allowed to procure) will also determine which capabilities they can use:

sm-6 block 1 - aaw
sm-6 block 1A - aaw, asuw
sm-6 dual 1, 2 - aaw, sbt-bmd
Very little is known about Dual I and even less about Dual II. Why wouldn't they be capable of ASuW ?

it's a possibility that they are indeed also gps equipped and have the software for asuw mode... but fwiw, the open source information so far is only about the aaw and sbt-bmd use for the dual-1,2 variants...

one could say:

sm-6 dual-1,2 - aaw, sbt-bmd, (asuw unknown)

Could be different mechanical's, warheads or even come down that it is too complex to try and fit all the coding to allow it to do everything into the one missile.

I think the benefits of standardizing on a single missile variant are compelling from acquisition and sustainment perspectives. AFAIK if you have the GPS h/w configured it's primarily having the 3 attack modes programmed into the missile. The blast fragmengation warhead would be effective against all types of targets.

it gets down to the logic boards... and if they are modular etc....

eg think of Mk48 ADCAP CBASS as an example, or Kerkanya.

(free plug for DT if you do the right search )

design and engineering principles are the same

Oh OK then, if there are unique boards to support the different attack modes then I can understand why there could be multiple variants deployed. Thanks

eg the target and discrimination library might be part of the (RISC based) logic controller - or it may not be an FRU item

we know dual-1 (sbt-bmd) came before block-1a (asuw), and dual-1 didn't have a gps receiver for it's sbt-bmd role

so the question would be whether they've now decided to include a gps receiver in dual-1,2 variants (plus the asuw s/w)... but so far I haven't found any open source info on a gps receiver being included for dual-1,2

Yes and as per GF's comments there may be other hardware dependencies aside from GPS. So we can hope more will be revealed in due time.

^and just as we are posting here about sm-6 and multi-role use, Thad Smith, raytheon's sm-6 business development director just said at the recent SNA 2017 symposium that starting later in 2017 the sm-6 missiles raytheon will be delivering to the USN will have all 3 (aaw, sbt-bmd, asuw) capabilities...

(Defense & Aerospace Report video published 01-11-2017)

https://www.youtube.com/watch?v=bifPZHiTKfY

so there it is, USN sm-6 deliveries in 2017 will support all 3 modes... maybe they will call this block variant sm-6 "triple-1", lol...

LOL.. Thanks for the confirmation. SM-6 wins the Blue Ribbon for versatility. Now build enough of them to halve the current $4M unit cost.

it also has the potential for ASAT

reuben james would indicate that it is AShM/ASM.
GPS is flagged for future inclusion.

I suspect that there is a high degree of modularity in this gen as they can be tested in silo

@GF, anti-sat? might you perhaps be confusing sm-6 with sm-3?... it was after all an sm-3 block-1a which was used in "Operation Burnt Frost" to bring down the US-193 satellite back in Feb '08...

am aware of that. the ability to upgrade SM6 for a variety of different missions is pretty self evident.
