An oropesa is a streamlined towed body used in the process of minesweeping. The role of the oropesa is to keep the towed sweep at a determined depth and position from the sweeping ship.[1][2][3][4] Oropesa are standard devices used on Avenger-class mine countermeasures ships.[5]
The device derives its name from the ship on which it was developed, HMS Oropesa, a converted British steam trawler.[6]
