MOSCOW — Russia’s global military ambition was on display Sunday when the country celebrated Navy Day with large military parades not only in St. Petersburg, but also off the coast of Syria.

The parades of ships, submarines and aircraft were held at Russian naval bases in Sevastopol, which Russia annexed from Ukraine in 2014, and at Tartus in Syria, where Russia is expanding its military presence.

The main parade took place in St. Petersburg, Russia’s second-largest city and home of the navy’s headquarters.
