170201-N-JX484-051 JACKSONVILLE, Fla. (Feb. 1, 2017) Colombian navy Type 209 coastal submarine Pijao (SO 28) arrives into the basin of Naval Station (NAVSTA) Mayport. The Pijao is visiting NAVSTA Mayport in support of the U.S. Navy's Diesel-Electric Submarine Initiative (DESI) which serves as a unique training conduit to enhance the fleet's ability to conduct anti submarine warfare (ASW). The participation of South American submarines in fleet training adds an additional degree of difficulty and realism to fleet ASW training exercises.
