Hellenic sloop-of-war Kartería (Καρτερία; Greek for "Perseverance") was the first steam-powered warship to be used in combat operations in history.

The vessel was built by Daniel Brent Shipwrights in the Greenland South Dockyard, Rotherhithe, London.

[2] It was financed mainly from the proceeds of the 2nd Greek Loan raised by the London Philhellenic Committee, but also by Capt Hastings' private funds.

The on-board furnaces that burnt coal to generate steam could also be used to heat cannon-shot to a red-hot state, creating highly incendiary missiles.

[4] Under the command of Hastings, the Kartería soon gained a fearsome combat reputation, taking part in numerous operations against the Ottoman Navy.
