The UVSRC attended the 15th International Submarine Races (ISR 15) at the Carderock Naval Warfare Center in Washington D.C. in 2019, with Chinook II. Chinook II took the prize for Most Reliable Submarine. Even though there were some technical difficulties such as a crash causing the main dome to shatter and broken props, Chinook II placed 5th overall. Additionally the electrical system, four-part hull design and tubercles (on the dive planes) were acknowledged with the Best Use of Technology award.
