As part of their missions to provide Maritime Security in the Somalia Basin and Gulf of Aden, Combined Task Force 151 (CTF 151) and European Union Naval Force (EU NAVFOR) Combined Task Force 465 (CTF 465) recently worked together in separate, yet complementary operations. CTF 151 conducted a counter piracy operation, named Operation WHANAU, which translates to ‘family working together towards a common goal’. While concurrently, CTF 465 conducted Operation Hopper.
These operations provided an excellent opportunity for the forces to work together to enhance regional maritime security by countering the threat of piracy. A key focus of Whanau was improved coordination between the 2 CTFs. (…)
