A surviving Titanic as a wartime troop transport

What might Titanic's later career look like if she survived a less serious iceberg collision?

She would probably serve as a fast troop transport in both world wars, while her accident influenced merchant rather than warship subdivision.

Warship design would change little because naval vessels already had more subdivision than contemporary liners. A less catastrophic collision might nevertheless accelerate the adoption of stronger transverse bulkheads in merchant ships. Titanic would be costly to operate as an armed merchant cruiser, so troop transport is the more plausible wartime role. An interwar conversion from coal to oil could also improve her speed and operating utility before a second wartime career.
