Black Hawk / Seahawk helicopters, bought in bulk: ~$10B across Army, Navy, and an ally in one contract (USAspending)

1The H-60 family as a common platform

The H-60 family — the Army's UH-60 Black Hawk and the Navy's MH-60S/R Seahawks — has long been the backbone of U.S. rotary-wing aviation. What makes this contract interesting is the bundling: multiple variants for different services, plus an allied (Bahrain) FMS tranche, all through one Army-run vehicle.

Buying aircraft that come off the same production line together stabilizes component purchasing and production planning and lowers per-unit cost — the same logic as the Navy's submarine block buys, expressed here as cross-service, export-inclusive bundling.

2How a multiyear contract works

Multi-year contracts commit to several years of quantities beyond the single-year budget cycle: the manufacturer gains bulk component buys and stable employment planning, the government gains a discount. The trade-off is binding future budgets, so congressional approval requirements are strict and "did it really save money?" scrutiny never goes away.

This contract\'s 2007–2016 performance and ~$10 billion cumulative value show what H-60 procurement looked like when the approach was at its height.

3Production after the Sikorsky acquisition

Sikorsky was acquired by Lockheed Martin in 2015, bringing H-60 production under its umbrella. Lockheed\'s position atop this site\'s contractor rankings rests not only on the F-35 but also on this kind of long-running rotary-wing demand.

4What is bundled into one contract

What makes this contract interesting is that variants belonging to different services, together with an allied nation's share, are gathered by the Army into one vessel for ordering. Aircraft off the same production line are bundled across the differences in who is buying.

Buying together steadies material procurement and production planning and holds down the price per aircraft — the same logic as block buying submarines, taking here the form of crossing services and mixing exports. A multiyear contract commits several years of quantity beyond the constraint of a single-year budget: the manufacturer gains bulk purchasing and stable employment planning, the government gains a discount.
