As a former Royal Navy officer who had the pleasure of serving with the U.S. Navy at sea, I have perhaps unique insights into the differences between how the U.S. Navy and Royal Navy train their junior officers. The differences between the Britannia Royal Naval College (BRNC) at Dartmouth and the U.S. Naval Academy (USNA) have been significant since the beginning of both institutions.
Dartmouth is not a degree-awarding institution like USNA. It solely is dedicated to the mission of training young naval officers for sea duty. BRNC concentrates on hands-on seamanship training and leadership, including all the necessary professional skill sets needed on board modern warships—from navigation, shiphandling, and nuclear/biological/chemical defense, to marine and electrical engineering, leadership skills; how to be a good junior divisional officer; dealing with unstructured challenging situations; and being toughened in rigorous physical environments for the challenges of fighting at sea.
