St. Hewlett is an industrialized city in the Osean Federation, east of Akerson Hill in a gulf of the Ceres Ocean. The city features a prominent port known as Port St. Hewlett, which serves as the home of the 3rd Osean Naval Fleet.
On September 27, 2010, the government of the Union of Yuktobanian Republics declared war on Osea and simultaneously launched a bombing raid on St. Hewlett. Their objective was to destroy the port facilities and the 3rd Osean Naval Fleet, particularly its flagship at the time, the OFS Kestrel.
The OADF Wardog Squadron and the OMDF VFA-206 squadron flew to defend the port and the Kestrel. Despite numerous naval losses and significant damage to St. Hewlett, the Kestrel and several other allied warships managed to escape the port into safe waters.
During the Lighthouse War, Port St. Hewlett was one of many Osean naval ports struck by Erusea's drone attacks. All of the aircraft carriers stationed in the port sustained heavy damage in the attacks.
- The naming of St. Hewlett implies that there was a "Saint Hewlett" at one point on Strangereal's Earth. This implies the existence of religions in Strangereal, alongside other hints such as the celebration of Christmas in Griswall, Aurelia.
