Long after they were flown by Army pilots to track enemy advances in the jungles of Vietnam, after they were traded to National Guard units and then declared obsolete for military use, the OH-58 helicopters were quietly transferred to small airfields across America.
Four of them landed at Lee Airport in Edgewater.
They were gifts to the Anne Arundel County Police Department from the U.S. Department of Defense, which in the mid-1990s was reassigning the retired aircraft to law enforcement agencies as part of the domestic drug war.
FOR THE RECORD - PLEASE READ MEMO.
At first, the issue was how police would use the old military helicopters. But the question being asked today by some local law enforcement officials is: How could they live without them?
Hundreds of county police and sheriff's departments amassed small air forces through the federal program.
Baltimore County police have seven helicopters -- four in service, three in reserve. Anne Arundel police, who recently agreed to allow Howard County police to use their fleet, have two helicopters in service. Two others are still painted Army-issue green -- one of which may soon be rotated into use.
The OH-58s are part of daily police operations, used to chase carjacking suspects, search for missing children and investigate sites of drug production.
But as the aging aircraft finish their last tour of duty in suburbia, police pilots have begun to study replacement options for the helicopters, which retail for about $1 million new.
Anne Arundel police spokesman Charles Ravenell said new helicopters are not in the budget because they aren't needed immediately. Although police in Baltimore and Anne Arundel counties have begun lobbying for funds, the future of the aviation units is uncertain.
"We'll probably be able to use ours for another four years or so," said Baltimore County police officer and pilot Roger Young. "But after that, it becomes a safety issue."
Structural integrity can be compromised as the helicopters approach 40 years old, pilots and mechanics say.
"I don't know what will happen," said Anne Arundel police Cpl. Larry Walker, who commands the police aviation unit. "But with all the traffic and congestion in this area, and with so many major events in our area, the helicopter is fast becoming the law enforcement tool of the future."
While most planes can fly about 300 days of the year safely, the OH-58, also called Bell 0H-58 Kiowas, can be flown safely 335 days, Walker said.
