My first thought too, because of the guns, but they're too close together. Interesting scene, American B-25 and a British P-51 in background (early model - P-51B?)
Well, it's not a B-25 I responded to the original post before reading @CAC's latest. The RAF did fit some of its Mustangs with four 20mm.
ANCIENT GREEK TRIREME 'OLYMPIAS' IN HELLENIC NAVY (PRESENT TIMES) Olympias is a reconstruction of an ancient Athenian trireme and an important example of experimental archaeology. It is also a commissioned ship in the Hellenic Navy of Greece, the only commissioned vessel of its kind in any of the world's navies.
I don't think the rowers did any fighting. They were merely propulsion. Fighters, and there were plenty, fought, slaves were the rowers.
The rowers would be cold...and in any rough seas wet also...No cover on the top deck...Not comfotable. The rowers would spend their energy getting flank speed to ram the opponent with that bow...
Rowing was a energy pit, true, but sails were available. Doldrums brought out the oars, as well as "RAMMING SPEED". No wind, you had to row if the currents weren't in favor. Transfers of kinetic energy required a surplus of that energy to make any impression on the other chap. Also, you have to be going faster than the currents if you want to steer. I'm not recalling if triremes could tack. Anybody?
Okay I see y'alls point but just to be obnoxious; I count over 60 men manning the oars and Six? Nicely dressed, I assume officers, standing around 'Commanding' . There appears to be open area between the slackers sitting down in the shade out of the sun, so where are the warriors ?
Crew. The total complement (plērōma) of the ship was about 200. These were divided into the 170 rowers (eretai), who provided the ship's motive power, the deck crew headed by the trierarch and a marine detachment. For the crew of Athenian triremes, the ships were an extension of their democratic beliefs. The trireme is said to have been capable of reaching speeds greater than 7 knots (8 miles per hour, or 13 km/hr) and perhaps as high as 9 knots under oars. Above the rowers, perched on the open top of the trireme, would be up to 30 hoplite infantrymen. Once the trireme had engaged with the enemy ship, either by ramming it or running along side it, these soldiers would attempt to board the opposing vessel and fight in hand-to-hand combat. Early Marines!
