Only just 6.5% of personnel account for women in the Naval Service but for the first time in its history, three of its ships - a third of the fleet - are being captained by female Lieutenant Commanders.
As the Irish Examiner writes, Nessa Maloney commands the LE Ciara, Grace Fanning is captain of the LE Roisin and Clare Murphy commands the LE Niamh.
Only the Army has a bigger percentage of female members, currently standing at 6.93%, while the Air Corps lags behind at just 4.5%.
The most senior officer in the Army is Colonel Maureen O'Brien, who is expected to climb the ranks even higher.
In the Air Corps the most senior women holds the rank of commandant.
