Four Typhoons from IX(B) Squadron, based at RAF Lossiemouth, flew into Mihail Kogălniceanu airbase on the Black Sea Coast.
From there, the jets will carry out the NATO enhanced Air Policing (eAP) mission for this summer's deployment.
The mission will see the RAF help protect the alliance's airspace in the region.
Wing Commander Lamping is Commanding Officer of 121 Expeditionary Air Wing, the unit that arrived in Romania ahead of the Typhoon's deployment, as well as being responsible for operating the aircraft.
He said the return to Romania is "to reassure our allies that the UK is fully committed" to securing NATO skies.
"This defensive Air Policing mission in the Black Sea region is very similar to UK Quick Reaction Alert, so the pilots and supporting personnel are experienced operators when it comes to delivering NATO Air Policing," he said.
"Despite the difficult circumstances caused by COVID-19 we are well prepared and ready to deliver the mission."
The mission enhances the national Air Policing conducted by the Romanian Air Force as part of NATO's collective air defence system.
IX(B) Squadron detachment is made up of personnel from across the service to form 121 EAW – consisting of about 180 personnel delivering the enhanced Air Policing role.
This RAF deployment is the third time the UK has deployed on the Air Policing mission.
Earlier this month, personnel from RAF Wittering started to move equipment to Romania ahead of the deployment.
The RAF says all necessary measures have been taken to ensure that both UK and Romanian mandated COVID-19 precautions are being followed.
