About PSC 4220 federal contract activity
PSC 4220, Marine Lifesaving and Diving Equipment, accounts for 42.27 billion in obligated spending across 137,271 awards over the last 10 years, with an average award value of 307,962.67. The volume of awards and the scale of obligations indicate a high-activity procurement category with recurring replenishment and equipment support needs across multiple federal customers.
Agency demand and leading federal buyers
The Defense Logistics Agency dominates activity in this PSC, with 42.01 billion obligated across 133,147 awards, representing the overwhelming share of both dollars and transaction volume. The Department of the Navy, USSOCOM, the Department of the Army, and the U.S. Coast Guard follow at much smaller levels, indicating that operational maritime and diving requirements are present across defense and maritime agencies but are concentrated primarily in DLA-managed procurement.
Vendor concentration and leading contractors
ATLANTIC DIVING SUPPLY, INC. is the clear lead vendor in this category, with 27.75 billion obligated across 75,042 awards, far exceeding all other vendors listed. W. S. DARLEY & CO., NOBLE SALES CO., INC., and SUPPLYCORE INC. also show substantial recurring business, while the appearance of both W. S. DARLEY & CO. and W S DARLEY & CO. suggests a vendor-name normalization issue that may split otherwise related obligations across duplicate records.

Annual obligations remain elevated in the most recent years shown, rising from 3.29 billion in 2021 to 7.49 billion in 2025, with a high point in 2025 among the provided data. Award counts also remain consistently high, ranging from 12,748 in 2021 to 16,978 in 2024, which suggests sustained procurement demand rather than isolated spikes.

Insight
PSC 4220 obligations over the last 10 years are highly concentrated among a small set of vendors, with ATLANTIC DIVING SUPPLY, INC. alone accounting for 27.75 billion of 42.27 billion total obligated. A second tier follows at much lower levels, led by W. S. DARLEY & CO. at 4.15 billion, while the remaining listed vendors each hold roughly 1.60 billion or less, indicating a steep drop-off after the top supplier. Duplicate vendor entries under different name formats, including W. S. DARLEY & CO. / W. S. DARLEY & CO and ATLANTIC DIVING SUPPLY, INC. with and without a CAGE code, suggest vendor normalization may affect concentration analysis.
