1917 politics
U-boats and US entry.
Prize law's wound. Convoy as a habit. Hidden nuclear second-strike as a political fact of the late twentieth century.
A ROK shipbuilding chapter.
Lessons
Pacific tonnage
A logistic decision.
SSBN
Hidden deterrent.
Keep the cost as a range
not a war -- merchant and navy dead sit on U-boat and Pacific war ledgers Submarine is not improved by a fake precise integer.
Memory is national
US/UK/AU/CA rites and the memory of Atlantic 1914-45, Pacific 1941-45, then a nuclear-deterrent undersea will not match. Name the difference when teaching Submarine.
Unresolved
Census still a band
"not a war -- merchant and navy dead sit on U-boat and Pacific war ledgers" remains a band. New archives refine Submarine; they do not un-happen 1900s-present (as a war type; ancestors earlier).
Archives uneven
Files on Submarine remain unevenly open across Atlantic 1914-45, Pacific 1941-45, then a nuclear-deterrent undersea. Hyman Rickover's paper trail is not the same as John Philip Holland's.
Chang Bogo
ROK Type 209 class name -- industrial history.
Teaching hours
English classroom hours on Submarine still disagree with hours in Atlantic 1914-45, Pacific 1941-45, then a nuclear-deterrent undersea. Is this a how-to? is often the gap.
Shifts
First U-boat war
1900-18: Law and food.
Second U-boat / Pacific
1939-45: Tonnage wars.
More operators
After 1991: ROK KSS; accidents as memory.
Afterlife of the name
Submarine left institutions and stories that outlasted 1900s-present (as a war type; ancestors earlier). John Philip Holland became a caption; Atlantic 1914-45, Pacific 1941-45, then a nuclear-deterrent undersea kept the rubble or the letterhead.
Outlook
Scholarship
New archives will refine Submarine (US Pacific boats, ROK Chang Bogo) without un-happening 1900s-present (as a war type; ancestors earlier).
Memory handover
As witnesses die, museums and film carry Submarine. Karl Donitz and Dudley Pound / Atlantic will keep being recast.
This atlas
Submarine stays a historical file -- type history, not a live order of battle or a method.
Risk
type still in service
Submarines remain in many navies. This page is not a hunting, diving, or construction guide, and not a live patrol tracker.
The ICBM page is the land cousin of the SSBN.
The carrier page is the surface argument partner.
