Along with the increased expense and difficulty in maintaining the Mi-17 helicopter fleet, utility helicopters are in high demand and the required maintenance exceeds current capacity and capability, leading to maintenance backlogs and a reduced number of aircraft available. Included in the recapitalization effort is an initiative to transition the force away from Russian-made Mi-17 helicopters to more reliable, cost-effective, and easier to sustain U.S.-made UH-60 helicopters.
I wonder if those UH-60As, refurb'd, will go through an A-L mod or remain in the A configuration. There's a difference in Max Gross Weight of 1700+ pounds. (At least according to the little cheat sheet I keep from an old Sikorsky blurb on A, L, and M).
