The Army has yet to present a formal acquisition plan for the LRHW 2.0 so we don't really have any insight into how and in what quantity it plans to employ it. OpFires with its large magazine and tactical flexibility is probably a better long term option. Perhaps a US Army and USMC OpFires based solution could be bought in quantity towards the second half of the 2020's.
That said, I'd much rather focus hypersonic acquisition investments towards the AF and Navy programs. The former needs both air-breathing and boost glide, while the latter needs to speed up VLS integration and perhaps look at integrating an AB hypersonic cruise missile on its strike fighter fleet. I would much rather this current upswing in defense budgets be used to bring that to fruition than to advance everything and put really nothing into a sustainable acquisition program going into the other side of the budget cycle. The Army LRHW etc is outside of its LRPF portfolio. PrSM, GMLRS-ER, Next Gen precision artillery rounds and the strategic fires cannon is probably a more important capability IMO. If they can bring all of these into operational service that would be a substantial achievement.
