About PSC 4220 federal contract activity
PSC 4220, Marine Lifesaving and Diving Equipment, recorded $28.17 billion in obligated spending across 77,272 awards over the last 5 years, with an average award value of $364,608.95. The category is highly concentrated and supports a large volume of recurring procurements tied to operational and readiness requirements.
Agency demand and leading federal buyers
The Defense Logistics Agency dominated activity in this PSC, accounting for $28.10 billion and 75,990 awards, making it the primary driver of market demand. The remaining obligated dollars were distributed across the Department of the Navy, USSOCOM, the Department of the Army, and the U.S. Coast Guard, each at a much smaller scale and with materially lower award counts.
Vendor concentration and leading contractors
Atlantic Diving Supply, Inc. was the clear market leader with $18.84 billion and 45,040 awards, indicating sustained concentration of spend with a single supplier. W. S. Darley & Co., Noble Sales Co., Inc., and SupplyCore Inc. also captured substantial obligations, and the duplicate W S DARLEY & CO. entry under the same CAGE suggests vendor name variation that should be normalized when assessing supplier concentration.
Annual contract trend over the analysis window
Annual obligations increased each year in the analysis window, rising from $3.29 billion in 2021 to $7.49 billion in 2025. Award counts also remained high throughout the period, peaking in 2024 at 16,978 awards and staying above 15,000 in both 2024 and 2025, which indicates sustained procurement intensity even as annual obligated value expanded.
How to interpret this page
This summary uses FPDS award data for PSC 4220 over the last 5 years and aggregates obligated dollars, award counts, and top agency and vendor totals. Vendor entries are presented as reported in FPDS; where name variants share a CAGE code, they may reflect the same supplier recorded differently across awards.

Insight
PSC 4220 obligations over the last 5 years total $28.17 billion across 77,272 awards, with activity highly concentrated among a small set of vendors. ATLANTIC DIVING SUPPLY, INC. alone accounts for $18.84 billion, or about two-thirds of total obligations, while the next largest vendors each remain below $3.0 billion. The vendor list also shows naming/CAGE overlap—such as W. S.
