In 1944 , Argentia served as one of the two stopover bases for the refuelling , maintenance , and crew changes of the six United States Navy ( USN ) K-class blimps that made the first transatlantic crossings of non-rigid airships . Blimps K-123 and K-130 from USN Blimp Squadron 14 ( also known as ZP-14 , Blimpron 14 , or " The Africa Squadron " ) left South Weymouth Naval Air Station in Massachusetts on 28 May 1944 and landed at Argentia about 16 hours later . The two K-ships then flew for approximately 22 hours to Lages Field on Terceira Island in the Azores , the second stopover base for the transatlantic flights . The last leg was a ~ 20-hour flight to the squadron 's final destination with Fleet Air Wing ( FAW ) 15 at Port Lyautey , French Morocco ( now Kenitra , Morocco ) . Blimps K-123 and K-130 were followed by K-109 and K-134 then K-112 and K-101 which left South Weymouth on 11 and 27 June , respectively , in 1944 . These six blimps initially conducted nighttime anti-submarine warfare operations to complement the daytime missions flown by FAW-15 aircraft ( PBYs and PB4Y-2 ) using magnetic anomaly detection to locate U-boats in the relatively shallow waters around the Strait of Gibraltar . Later , ZP-14 K-ships conducted minespotting and minesweeping operations in key Mediterranean ports and various escort missions including that of the convoy carrying Franklin Roosevelt and Winston Churchill to the Yalta Conference in early 1945 . In late April 1945 , K-89 and K-114 left NAS Weeksville ( now Coast Guard Air Station Elizabeth City ) in North Carolina and flew a southern route to NAS Bermuda , the Azores , and Port Lyautey , where they arrived on 1 May 1945
