Pagination or Media Count:
The Norwegian Radar Chronograph Set NM87 was evaluated by Frankford Arsenal from November 1972 through March 1974 to determine the capability of the NM87 to chronograph standard cannon artillery. The NM87 was subjected to laboratory, environmental, and firing tests. From the results obtained to date, it is concluded that this chronograph is simple to operate, reliable, requires little maintenance, and is capable of the same order of precision as is possible with the M36 Radar Chronograph Set which is the item currently used for muzzle velocity measurements. The report indicates some limitations and recommends improvements for utilization of the equipment.
