Capt. Justin Harts relieved Capt. Walter C. Mainor as Commander, Task Force (CTF) 71 and Commander, Destroyer Squadron (DESRON) 15. Mainor assumed command in August 2022, and will be reporting as the direct advisor for the Chief of Naval Operations N17 Diversity, Equity, and Inclusion office in Washington, D.C.

"While our adversaries challenge freedom, stability, and international law, the ships of Destroyer Squadron 15 and Task Force 71 continue to safeguard the seas and our national interests,” said Mainor. “We've bolstered our alliances in the Indo-Pacific region and enhanced our collective maritime readiness to maintain deterrence and promote respect for sovereignty. The steadfast commitment of our Sailors guarantees the readiness of our ships to aid our nation, allies, and partners at a moment's notice. It has been an honor and privilege to lead them as their commander."

During his tenure, Mainor led DESRON 15 through patrols on USS Blue Ridge (LCC 19) and USS Ronald Reagan (CVN 76) as the theater surface warfare commander for U.S. 7th Fleet. Additionally, he was responsible for the surface ships operating independently across the fleet. Mainor’s other major accomplishments include bilateral and multilateral exercises with partner and allied nations, freedom of navigation operations, and strait transits in support of a free and open Indo-Pacific.

Mainor received the “Legion of Merit” for his exemplary performance from August 2022 to November 2023. He was also presented the Defense Cooperation Medal by Vice Adm. FUKUDA Tatsuya, Commander, Fleet Escort Force, Japan Maritime Self Defense Force, in honor and recognition of his contributions to sustained readiness, enhanced interoperability and overall strengthened resilience of the US-Japan alliance.

Harts served as DESRON 15’s deputy commander prior to assuming command.

“It has been absolute honor to help fulfill Capt. Mainor's vision for CTF 71 over the last 18 months; I've been in awe of this staff’s ability to orchestrate the combined operations of our allied and partner surface navy operations,” said Harts. “On any given day, our destroyers and cutters are operating alongside ships from many nations, as well as a growing list of new partner navies who are eager to pitch in. These operations are, and will remain, the most tangible example of the international community's shared commitment to a free and open Indo-Pacific. We have maintained a constant presence in the region and I am excited to have the opportunity to continue our support of these relationships into the future.”
