Romania has been a bit of an odd duck historically. It has the dubious honor of being home to Vlad the Impaler (the inspiration for Dracula) and, under the Ceausescu regime, went its own way at times while nominally a member of the Warsaw Pact, even going as far as buying French equipment during the Cold War (which it refused to let the Soviets examine).
Now a NATO ally, Romania has been making do with a lot of ships that use old Soviet technology. Their most modern vessels are two heavily-modified British Type 22 Batch 2 frigates that have had their Sea Wolf surface-to-air missiles removed. Their most powerful ship is the 33-year-old destroyer Marasesti, armed with eight SS-N-2 Styx anti-ship missiles, two triple 533mm torpedo tube mounts, four AK-630 Gatling guns, and two twin 76.2mm AK-726 dual-purpose guns.

That could be changing soon, however, according to a report by DefenseNews.com. Romania is now seeking to buy three submarines to replace its lone Kilo-class vessel, the Delfinul, and four new surface ships. While Romania has made no decision on which submarine design it will buy, it did, at one point, plan to buy four Sigma-class corvettes from the Netherlands.
The previous purchases indicate that the Romanian Navy may be looking to replace their Tetal-class corvettes. The corvettes, three of which were built in the 1980s, are armed with one or two twin AK-726 mounts, two twin 533mm torpedo tube mounts, and 30mm cannon, among other systems. Two of the Tetal-class corvettes can operate helicopters off decks.

Romania has also ordered 227 Piranha V infantry fighting vehicles. These eight-wheeled vehicles are comparable to the M1126 Stryker, with a crew of three and the ability to haul eight infantrymen.
Though it's impossible to say exactly which upgrades Romania is to acquire, modernization seems to be an inevitability.
