Maryland State Police are set to accept delivery of six new helicopters at Martin State Airport this week.
The AW139 helicopters are among 10 AgustaWestland helicopters the department will get to replace its aging fleet of 11, according to a statement from the organization.
All but one of its current fleet is at least 20 years old.
Two helicopters were scheduled to be delivered Monday; the rest will be delivered Tuesday and Wednesday, according to state police officials.
Training will begin immediately, though the helicopters will not be in use for medevac flights or other missions until late spring or early summer.
The new helicopters will allow state police aviation command "to continue its unique multiple mission capability of medevac, search and rescue, law enforcement, and homeland security," officials said in a news release.
