I overlooked this when I wrote (repeatedly) about the merge between field artillery and air defence:

Well, I can't know everything. Still, I'm a bit disappointed that nobody pointed at this in comments.
This waswritten published by me mere days after the Polish article:

*self-praise*
At least some of my writing about the merge was earlier than the article above:

*/self-praise*
I suppose now I can wait till I find official references to my other air defence favourites; RCWS for the dispersed low level counter-drone fight.

I wrote a while ago about how much Western military equipment isn't meant to function well at -30°C, and how this could open a window of opportunity for successful aggression. Colder than -20°C is actually rare in the relevant areas of NATO, though. The question remains whether the 'more extreme weather' facet of climate change / global warming will push this issue more to the forefront, and will Western armed bureaucracies respond well?

New START up next. Someone told the US that intermediate range missiles cant reach from CONUS to Chinese boom chuckers. Who knew how large the Pacific Ocean is? I didn't. Its unfair to expect that anyone else knew either.
ReplyDeleteSo can they swap? Restart the INF and kill New START instead? I'll ask Putin.
I also like the idea of a common rocket artillery and air defense infrastructure. As it so happens, 160mm LAR-160/Accular rockets are 3.4-4 meters long; 227mm GMLRS, ~380mm LFRP, and 610mm ATACMS missiles are all 3.94 m long; ESSM is 3.66 meters long; and NSM/JSM is 3.95m long.
ReplyDeleteA new 4.0-4.5 meter height “self-defense” version of Mk 41 or Mk 57 VLS could potentially allow navies and armies to utilize common launch canisters for air defense and land-attack missiles. A 2-3 cell-abreast version of Mk 41 (e.g., a smaller version of the angled, deck-mounted concepts) or Mk 57 VLS version should be road-mobile. Updated versions of the BMG-109G launcher could utilize the tactical and strike length Mk41 VLS or Mk 57 canisters for longer-ranged munitions.
In a naval context, a ~4 meter height Mk 57 VLS style system could be easily mounted along the periphery of helicopter landing decks as on the Zumwalt-class destroyers so that the bow-mounted VLS cells can be reserved for full-height/length canisters (e.g., SM-3/6, TLAMS, LRASMs, new UUM-125-type ASROCs, and 2-stage, long-range ESSMs).
I’m also a proponent of utilizing 152-160mm rockets for naval applications. If NGFS is a requirement, this size of rocket could be used for launching PGMs instead of the equivalent artillery shells atop 5/6+ zone charges. They could also be packed 9 to a single Mk 41 canister. This would extend barrel length by reserving 127-155 deck guns for short-range area targets and thereby increase magazine depth because fewer charges need to be carried. Moreover, at lower energy levels a rifled coil gun may be practical at the power and energy densities of present technologies. This sort of utilization should also apply to land-forces.
DeleteI’ve seen Mk 31 GMLRS missiles quoted at about $100K per missile. M982 Excalibur purportedly costs about $68K per round (wiki). It seems as though adding a guidance package increase costs far more than adding a rocket motor to the rear of a dumb or smart warhead.
M982 is just shy of 1 meter long. A zone-6 charge is also about 1 meter long. M982 can achieve ranges of about 40 km atop a zone-5 charge and 45-50 km atop a zone-6+ “super” charge. A 4.0 meter 160mm Accular missile achieves a range of 40 km launching a 35 kg warhead. The M982 warhead is only 22 kg according to the source below. Accordingly, a 160mm missile 4.0 meters longs is roughly twice as long as a 155mm projectile and charge that achieves the same range, but the missile delivers a 159% more massive payload. So versus a maximum range 155mm shot, the opportunity cost of carrying a 160mm rocket in place of a 155m shell is roughly 1 155mm shot for every 2 160mm missile. Factoring in the expense of purchasing, maintaining, and moving a 50+ caliber gun tube and an autoloader capable of approaching the missile systems MRSI rate of fire, I think chasing 40+ km performance from 155mm tube artillery is misguided.

152-160mm rockets could also carry some ineresting, less conventional payloads.
DeleteA and G sized sonobuoys, for example, are less than 127mm in diameter, as is Raytheon’s Coyote UAV. As stated above, 4.0 meter 160mm Accular rockets are capable of launching a 35 kg warhead to 40 km. The AN/SSQ-565 multistatic low frequency active sonobuoy is probably the heaviest A-sized sonobuoy at 14.4 kg for the bare buoy, and it already comes equipped with a GPS receiver.
A 4.0 meter 160mm rocket launching a relatively light 1 meter-long, gee-hardened sonobuoy payload should be able to launch the sonobuoy on a mostly ballistic trajectory to first CZ distances (i.e., ~50 km), much like the BTERM, ANSR rocket-assisted projectiles. Much of technology for high altitude P-8 sonobuoy deployment could be reused to slow down the sonobuoys enough to survive water-entry. Adding wings to the payload section like the ground-launched small diameter bomb or the HAAWC torpedo might extend the range to second CZ distances at the expense of a much longer time of flight (i.e., see BTERM/ANSR vs ERGM/LRLAP). A coyote UAV could be launched behind a handful of sonobuoys (e.g., a bathythermal buoy, at least one active buoy, and a handful passive buoys) to relay data back to the ship like the old DASH UAVS. A single short, 4-5 meter Mk 41 canister could therefore enable a relatively small surface-vessel to lay a usable sonobuoy field at 1-2 CZ distances.
