Which geographic regions had the highest number of US Coast Guard drug interdictions in 2024 (Caribbean, Eastern Pacific, Gulf of Mexico, Atlantic)?

1. Eastern Pacific: where the biggest bulk hauls were reported

Reporting and Coast Guard commentary cited in secondary sources place the Eastern Pacific at the center of the Coast Guard’s largest 2024 sea‑borne cocaine seizures, including multiple Operation Pacific Viper interdictions and a year total the service credited with intercepting 106.3 metric tons of cocaine at sea in 2024 ^[1]. News coverage of record single‑boat hauls — for example a multi‑ton seizure by the cutter Munro in the Eastern Pacific — reinforces that the largest bulk seizures occurred there ^{[4] [1]}.

2. Caribbean and the Western Hemisphere transit zone: heavy operational focus but mixed metrics

Congressional and Department of Homeland Security reporting describes significant Coast Guard activity in the Caribbean and the broader Western Hemisphere Transit Zone, and notes the service is a major interdiction asset for the region ^{[5] [2]}. Oversight material stresses sustained focus on the Caribbean littoral and cooperation with regional partners, but the supplied documents do not enumerate a 2024 regional breakdown of interdiction counts by Caribbean versus other zones ^{[5] [3]}.

3. Gulf of Mexico and Atlantic: quieter in the supplied reporting

The search results emphasize Districts 7 and 11 for most known maritime drug flow and highlight the Eastern Pacific and WHTZ; explicit, sourced counts tying the Gulf of Mexico or the broader Atlantic to the highest number of interdictions in 2024 are not present in the materials provided ^{[3] [5]}. Available sources do not mention a clear, higher interdiction tally for the Gulf or Atlantic that would outrank the Eastern Pacific ^{[1] [3]}.

4. What the official numbers say — and what they don’t

The Coast Guard’s fiscal‑year reporting and related government documents supply aggregate measures — for example the 106.3 metric tons figure for Coast Guard‑intercepted cocaine in 2024 and the agency’s drug‑disruption rate of 73% for FY2024 — but do not, in the sources you supplied, present a straightforward table that ranks interdiction counts by the four named regions (Caribbean, Eastern Pacific, Gulf of Mexico, Atlantic) for 2024 ^{[1] [6]}. Congressional testimony and GAO oversight focus on mission challenges and asset needs rather than a regional leaderboard ^{[2] [7]}.

5. Competing interpretations and hidden emphases

News and opinion outlets emphasize spectacular Pacific hauls and Operation Pacific Viper results ^{[1] [4]}, which can create the impression the Eastern Pacific was the dominant locus of interdiction activity in 2024. Oversight documents and Coast Guard statements stress long‑running partnerships, interdiction across the transit zone, and capability gaps that affect all regions — an implicit reminder that seizure volume can reflect asset posture and operations ^{[7] [2]}. These differing emphases reflect competing agendas: operational success narratives versus accountability and capability narratives ^{[1] [7]}.

6. Bottom line and how to resolve the remaining uncertainty

Based on the supplied sources, the Eastern Pacific is the clearest candidate for having the highest‑volume seizures in 2024, supported by the Coast Guard’s 106.3 MT seaworthy intercepts and multiple high‑profile Pacific interdictions ^{[1] [4]}. However, the materials you provided do not include a complete, region‑by‑region count of interdictions (Caribbean, Eastern Pacific, Gulf of Mexico, Atlantic) for 2024, so a definitive ranked list by number of interdictions cannot be produced from these sources alone — available sources do not mention a full regional breakdown for 2024 interdiction counts ^{[1] [3]}. For a definitive ranking, request the Coast Guard’s FY2024 counterdrug annex or DHS interdiction dataset that breaks interdictions down by operational region (not found in current reporting; ^[1]; ^[6]3).
