Just some very very arbitrary calculations with the assumption that there is adequate procurement and production existing or near term anti-ship munitions in the next few years, and that there is a robust C4ISR architecture present (JADC2). Seems plausible.
B-1B bomber fleet
Launching 8 maritime strike sorties every 24 hours for 72 hours with the remainder utilized to conduct strikes on land targets. Each maritime strike B-1B loaded with 24 LRASMs. 6 LRASMs allocated per target to ensure defense penetration: (8 x 3 x 24) / 6 = 96 enemy major surface combatants hit (mission kill).
USN CG/DDG fleet
50 allocated to PACFLEET currently, assuming 50% (25) surged forward due to rising hostilities. Each striking 3 enemy major surface combatants with multiple Maritime Strike Tomahawks and SM-6s in the 72 hour period. Remainder VLS tubes utilized for area air defense, land attack Tomahawks and Vertical Launched ASROCs: 25 x 3 = 75 enemy major surface combatants hit (mission kill).
SSN fleet: 30 assigned to PACLEET currently, assuming 50% (15) surged forward due to rising hostilities. Each striking 3 enemy major surface combatants with MK-48 ADCAP torpedoes, Harpoons or Maritime Strike Tomahawks within the 72 hour period. 15 x 3 = 45 enemy major surface combatants hit (mission kill).
Carrier-based aviation:
3 CAW present at commencement of hostilities, surging at 150 sorties per carrier per 24 hours. 20% of sorties are maritime strike sorties. Each maritime strike sortie aircraft loaded with two LRASMs or Harpoons or SLAM-ERs or JSOW-C1. 6 missiles per target to ensure defense penetration. (0.2 x 150 x 3 x 2) / 6 = 30 enemy major surface combatants hit (mission kill).
96 + 75 + 45 + 30 = 246 enemy major surface combatants hit (mission kill)
Lower end PLAN combatants, which makes up majority of their fleet, are significantly easier to kill and will not need six missiles per target to ensure a hit.
Other weapons available:
- LCS with 8 x NSM
- HIMARs with Cross-domain ATACMs
- USMC land-based Hornets with 2x Harpoons/SLAM-ERs/JSOWs
- USN P-8A Poseidons with 4 x Harpoons
As you can see, LRASMs, Maritime Strike Tomahawks and SM-6s are crucial and current production rates are lacking.
Number of ships that can be struck in 72 hours will improve further as US Army acquires their anti-ship PrSMs and land-based launchers for MSTs and SM-6s.
The entire JADC2 architecture needs to be beefed up significantly.
