** However, it seems that some of the world's historical events may have progressed as it did in real life regardless of the divergence above. One of such events was funnily enough, the [[https://en.m.wikipedia.org/wiki/Hyperinflation_in_Zimbabwe Zimbabwean Hyperinflation]], as evidenced by Kouko who have gotten hold of one of its banknotes, [[RuleOfFunny somehow]].

* MidSeasonUpgrade: The ''Harekaze'' is upgraded twice, with its [[https://en.wikipedia.org/wiki/12.7_cm/50_Type_3_naval_gun 12.7 cm/50 Type 3 naval gun turrets]] replaced by the faster-firing [[https://en.wikipedia.org/wiki/10_cm/65_Type_98_naval_gun 10 cm/65 Type 98 naval guns]] during the fourth episode, and by episode eleven, the Type 98 guns are replaced with the American [[https://en.wikipedia.org/wiki/5%22/54_caliber_Mark_16_gun 5"/54 Mk 16 naval guns]], which were designed to perform well in both anti-aircraft roles, as well as against smaller ships. These were first introduced as the secondary/anti-air armament for the US Navy's ''Midway''-class carriers, with some of these guns later being removed from the carriers and installed on the JMSDF's ''Murasame'' and ''Akizuki''-class destroyers.

* RidiculouslyFastConstruction: The ''Harekaze'''s Type 3 naval guns are replaced by the Type 98s within the span of a day, whereas in reality, it would take much longer to modify the turrets of the Type 3 to accommodate the turret ring of the Type 98 to preserve proper function. Similarly, ''Kagerou''-class destroyers were never designed to accommodate American-designed batteries without major modifications, but the new turrets are nonetheless installed in a speedy fashion during episode eleven, nor were they designed to accommodate German-designed batteries either, as is the case with the successor of the ''Harekaze'', the ''Okikaze'', which is armed with German [=150mm=] guns in single mounts.

** The ''Independence''-class Littoral Combat Ships are armed with the [[https://en.wikipedia.org/wiki/Bofors_57_mm_gun Bofors 57mm cannon]] in reality, and while the ''Sarushima'' is depicted with one earlier in the first episode, later closeups show the ''Sarushima'' as armed with the [[https://en.wikipedia.org/wiki/5%22/54_caliber_Mark_45_gun Mark 45 5-inch gun]], which is the primary armament for the [=JMSDF=]'s ''Atago''-class missile destroyers. The firing rate seen is consistent with that of the slower-firing Mark 45 -- the Bofors 57mm cannon's Mark I iteration is ten times greater.

** In episode nine, the girls initially believe an incoming vessel to the the ''Musashi'' but catch on when they spot its turrets as having two barrels rather than the three seen on ''Musashi'' because of the distinct tower-bridge on the''Hiei'', which was designed as a prototype for the ''Yamato''-class.

* CoolBoat: Amongst the naval vessels seen in ''High School Fleet'' include the IJN ''Yamato'', the ''Musashi'', the modified ''Independence''-class ''Sarushima'' (a Littoral Combat Ship), and the ''Deutschland''-class crusier ''Admiral Graf Spee''. The ''Harekaze'' is a fictional vessel that was inspired by the ''Kagerou'' class of destroyers and named after one of the three unbuilt ''Kagerou'' class destroyers that served as part of the dummy budget for the ''Yamato''.

A century after mining triggers a tectonic disaster submerging much of Japan, the nation has since recovered and thrived, constructing massive ocean-borne settlements along coastal areas. These cities are safeguarded by the Blue Mermaids, an elite, all-female organisation whose members have dedicated their lives towards the defense of ocean routes and civilian populations living along the coast.

When she was younger, Akeno Misaki made a promise with her best friend, Moeka China, to join the renowned Blue Mermaids. Akeno is admitted to Yokosuka Girls' Marine High School, where she is reunited with Moeka and assigned to be the captain for the destroyer ''Harekaze''. On her maiden voyage, however, Akeno and her crew come under fire from their instructor, and inadvertently become accused of mutiny. Finding themselves wanted fugitives, Akeno and her crew must rally to survive, and in the process, each member of the crew turn to their unique skills in order to help Akeno and the ''Harekaze'' navigate difficult waters, overcoming obstacles on the way to becoming full-fledged members of the Blue Mermaids.

* RefugeInAudacity: The tactics that Akeno resorts to in order to get the ''Harekaze'' and its crew out of difficult situations are over-the-top and surprise her crew when she suggests them. Against all odds, these plans work out, whether it be firing a shot to disable the ''Graf Spee'''s propeller by aiming for a target below the water line, or deploying the ''Harekaze'''s paravanes to disable a pursing I-201 submarine by tangling its propellers so it can be hit with a depth charge.

** Spirits are high during the tenth episode when the girls host an equator-crossing festival, closing as the girls perform [[CherubicChoira cheerful children's song]]. As focus shifts to Akeno standling alone, wondering if everyone will make it through their upcoming operation safely, the singing fades into a [[CreepyChildrenSinging hollow echo of the girls' voices]].
