NORFOLK – A 2000 Sewickley Academy graduate and Cincinnati, Ohio, native is serving in the U.S. Navy with Assault Craft Unit FOUR (ACU 4), one of the Navy’s most advanced amphibious warfare units.
Petty Officer 1st Class Ryan Crosby is a gas turbine systems technician (mechanical) with the group operating out of Virginia Beach, Virginia.
A Navy gas turbine systems technician (mechanical) is responsible for power plant operations on the boat and maintenance of half a dozen gas turbine engines.
“My favorite part of my job is the responsibility that I have to my personnel and my craft,” said Crosby. “I am second in command.”
ACU 4 is one of the components of Naval Beach Group TWO (NBG 2).
Commissioned in 1948, just after World War II, NBG 2 trains and equips military forces for deployment overseas. Sailors with NBG 2 serve a vital role in the Navy our nation needs by ensuring that amphibious operations remain ready to defend and protect America at all times.
ACU 4 operates landing craft, air cushion (LCAC) vehicles, which are specialized to transport personnel and equipment from surface ships to shore. The LCAC is a high-speed, over-the-beach craft capable of carrying a payload of more than 60 tons. The LCAC can be used to transport weapons systems, cargo and personnel of Marine assault units. Air cushion technology allows the vehicle to reach more than 70 percent of the world’s coastline, while only 15 percent of that coastline is accessible by conventional landing craft, according to Navy officials.
The exercises and real-world operations that ACU 4 sailors participate in include evacuation of American citizens from a hostile territory, delivery of food and medical supplies after a natural disaster, and many other tasks that involve movement from ships off-shore to the beach, according to Navy officials.
“The camaraderie is the best part of this command,” said Crosby. “We work together as a team to accomplish the goals.”
Jobs are highly specialized and keep each part of the command running smoothly, according to Navy officials. The jobs range from operating boats to maintaining engines.
"ACU 4 sailors and craft are the connector and where the rubber meets the sand between the Amphibious Ready Group and the fight,” said Capt. Erik Nilsson, ACU 4’s commanding officer. “The maintenance team is dedicated to ensuring the craft are ready at a moment's notice to engage in missions from high-end combat to humanitarian assistance and disaster relief.”
While serving in the Navy presents many challenges, Crosby said he and his family have found many great rewards serving in the military.
“The accomplishment I am most proud of is the birth of my children,” said Crosby. “I have two little girls, and they and their mother are my life. The Navy has allowed me to provide for them and I am very grateful for that.”
