Because the USS New Hampshire is a very modern warship she does not undergo any major refit/rebuild in the early-mid thirtys as earlier battleships do but instead receives a modest refit/upgrade in 1934.
1934 Refit II:
• Lower observation platform removed from main mast.
• Mk-34 GFCD added where 20' range finder was.
• 5”/25s replaced with 5”/38s.
• Airplane catapult on #3 turret upgraded.
• Stern boom floatplane retrieval crane replaced with newer crane.
