The first three Royal Australian Navy officers have graduated from U.S. Navy nuclear power school. The three officers -- two LCDRs and a LT, who are already qualified in RAN submarines -- will now complete training at a moored training ship and in the future will be assigned to Pearl Harbor-based Virginia class nuclear attack submarines.
This is the first step in the AUKUS plan to provide the RAN with SSNs.
