Site: PIN-3




  • PIN-3 on LADY FRANKLIN POINT, Canada, is situated at the summit of a small tableland which rises to about 50 feet above sea level. This Auxiliary Radar Station occupies 1487 acres at the western extremity of a 2.5 mile wide peninsula which extends 7 miles west southwest from Victoria Island. Extensive foot-thick peat swamps are on the peninsula.


  • Annual precipitation is variable, averaging approximately 8 inches. snowfall is about 47 inches a year. Absolute minimum and maximum temperatures are minus 53 and plus 68 degrees Fahrenheit.


  • A half-mile round trip potable water haul is maintained during summer when the shallow fresh water lake is free of ice. for winter, water is stored in a 65,000 gallon exterior tank. Hot water is circulated in the tank to keep the water from freezing.

Fire destroys North Warning System Radar Station
Nunatsiaq News

A mysterious fire on January 10 has almost completely destroyed a North Warning System radar station near Kugluktuk. The radar station, know as PIN-3, is located about 100 kilometres north-east of Kugluktuk at Lady Franklin Point on Victoria Island.

A team of investigators from the Department of National Defence in Ottawa were to have arrived at PIN-3 this week assess the damage, said Lieutenant Mark Gough, a DND spokesperson based in Yellowknife.

“We’re not really sure what happened,” Gough said. “It’s quite possible that there was a mechanical defect.”

Gough said teams that visited the site have found that close to 90 per cent of the radar station, including all of the electrical, radar and power generation equipment, have been destroyed by the fire.

He said later this week that the Canadian forces’ fire marshal will investigate the fire to find out what caused it.

Lieutenant-Colonel Brent Lamb, the head of North Warning System operations at national defence headquarters in Ottawa, said workers at NORAD headquarters in North Bay, Ontario noticed on Monday morning that something was wrong with the radar station.

Later that day, a team of Frontec Logistics technicians from Cambridge Bay flew to Lady Franklin Point in a helicopter to take a look at the site. They found that a fire had disabled the radar station, and was still burning its way through various buildings at the site.

Lamb said, however, that the loss of the site won’t affect the North Warning System’s detection capabilities in the Arctic.
