Strategic Sealift Officer (U.S. Navy Reserve)—2025

This guide provides helpful information for those looking to become a Strategic Sealift Officer during Fiscal Year 2025.

What is a Strategic Sealift Officer?

Strategic Sealift Officers (SSO) are commissioned officers in the United States Navy Reserve designated to provide strategic sealift during times of national defense or disaster.

Strategic Sealift Officer Program (SSOP) offers emergency crewing and shore-side assistance for Military Sealift Command’s Surge Sealift Fleet and the Ready Reserve Force during times of national defense or emergency.

“It is the policy of the United States that merchant marine vessels of the United States should be operated by highly trained and efficient citizens of the United States and that the United States Navy and the merchant marine of the United States should work closely together to promote the maximum integration of the total seapower forces of the United States.”

(46 USC 511)

History

The U.S. Navy has deep roots in the American Merchant Marine. From the American Revolution to World War II, Merchant Mariners played a critical role in naval operations.

  • Revolutionary War: Almost every Naval Officer and sailor came from the Merchant Marine.
  • Early Navy: Many of the first Navy warships were armed merchant vessels.
  • Training Tradition: Officers and midshipmen sailed on merchant ships to build seamanship skills.
  • Pre-WWII: The Merchant Marine was the Navy’s largest source of trained officers.

The Merchant Marine Act of 1936

Passed to ensure the U.S. always had a strong Merchant Marine ready to support the Navy and military in war or national emergencies.

The Birth of SSOP

  • On June 10, 2011, the Deputy Chief of Naval Operations for Fleet Readiness and Logistics approved the transition of the Merchant Marine Naval Reserve Program into the Strategic Sealift Officer Program (SSOP).
  • Before WWII, qualified Merchant Marine officers joined the Naval Reserve, stepping up to defend the country before the war even began.

The Merchant Marine and Navy have always been linked—from America’s earliest wars to modern-day naval strategy.

Crucial Link

At the end of World War II, the U.S. Navy had a much larger fleet than today. But one core mission hasn’t changed: protecting critical sea lanes in wartime.

How Strategic Sealift Became a Navy Priority

  • Since the 1980s, Strategic Sealift became a Navy-assigned mission—essential for moving military cargo and personnel.
  • With fewer Navy ships, the Merchant Marine plays a bigger role than ever.
  • MARAD and Military Sealift Command now operate government-owned ships with civilian crews to carry out sealift operations.

The Role of the Strategic Sealift Officer Program (SSOP)

SSOP exists to strengthen the bond between the Navy and Merchant Marine.

  • SSO officers are the key link between merchant and naval ships during joint operations.
  • They ensure sealift missions integrate smoothly into Navy operations.
  • Their expertise keeps critical supply chains moving in wartime and crisis situations.

With fewer warships, Strategic Sealift Officers are more essential than ever in keeping the Navy mission-ready.
