How much blood plasma does the USA ship aboard?
The US Navy's two Mercy-class hospital ships each carry up to 5,000 units of plasma and blood in their onboard blood banks — a capability rooted in WWII-era mass-production logistics pioneered by Dr. Charles Drew. The Defense Health Agency, per a June 2026 national forum, is now formalizing a 'Joint Force Blood Therapy Strategy' that emphasizes frozen platelets, walking blood banks, and forward-deployed resupply chains. A January 2026 peer-reviewed analysis in Transfusion explicitly frames military plasma as a 'strategic resource,' noting WWII processed 3 million pints of dried plasma — and warning future large-scale combat operations will recreate that demand pressure.
Evidence
- The two active US Navy hospital ships — USNS Mercy (T-AH-19) and USNS Comfort (T-AH-20) — each maintain blood banks holding up to 5,000 units of plasma and whole blood, according to verified Navy specifications.
- The historical architecture of this system traces directly to Dr. Charles R. Drew, honored by the naming of USNS Charles Drew (T-AKE-10), a Lewis and Clark-class dry cargo ship.
- The incoming Bethesda-class Expeditionary Medical Ships (3 hulls, $867.6M contract, Austal USA) are designed for speed — 30+ knots versus the Mercy-class's 17.5 — suggesting the strategic priority is now rapid plasma and blood resupply to contested zones, not just large floating hospitals.
- Both ships were moored together at Alabama Shipyard as of February 2026, with USNS Comfort having completed its 79-day Continuing Promise 2025 mission treating 12,616 patients across six countries.
- Drew's innovation, per War on the Rocks (July 2026), was transforming transfusion from a bedside, one-donor-one-patient act into a standardized bulk supply that could be produced industrially and shipped across oceans — the foundational logistics model still in use.
