Minister for Defence and Foreign Affairs, Simon Coveney, praised the "professionalism and pride" of the Defence Forces at a Naval Service commissioning ceremony in Haulbowline.
Four cadets of the 58th class were appointed to be Officers of the Permanent Defence Force.
Addressing the newly commissioned Officers, Minister Coveney thanked them for their commitment and service and recognised the contribution of the Naval Service and their support to the HSE during the Covid-19 emergency.
"In recent years there has been a growing awareness of the professionalism and capacity of the Naval Service and a justifiable pride in their service.
"We have all seen the pictures of members of the Naval Service rescuing migrants in the Mediterranean and more recently, we have witnessed the contribution of the Naval Service and the broader Defence Forces at home in supporting the HSE response to the Covid-19 emergency."
Minister Coveney encouraged all those seeking a career to consider serving in the Defence Forces and said that "recruitment is ongoing across a range of disciplines".
On Friday, the Minister also welcomed the re-enlistment of the first group of former personnel into the Army, Naval Service and the Air Corps.
The scheme to re-enlist former enlisted personnel, which launched back in April, is focused on those who have the skills and expertise required to fill identified gaps in the Permanent Defence Force.
The scheme allows for initial re-enlistment for a minimum of six months and up to three years.
Approving the re-enlistment of the first group, Minister Coveney welcomed the positive response to the scheme.
"It is heartening to see the level of interest from former personnel since the scheme was launched and I believe this demonstrates the sense of service among members of the Defence Forces as well as the enduring appeal of a career in the Defence Forces.
"I look forward to receiving further recommendations from the Chief of Staff for the re-enlistment of further groups into the Permanent Defence Force," he said.
"This scheme represents one of the range of actions being pursued to address the skill shortages in the PDF and as Minister for Defence, I extend a very warm welcome back to those re-joining," Minister Coveney continued.
Since April, some 637 applications have been received with over 515 applications going forward for further assessment by the Chief of Staff.
