|Test site||Nevada Test Site|
|Number of tests||48|
|Max. yield||38-200 kt|
|Previous test||Operation Niblick|
|Next test||Operation Flintlock|
Operation Whetstone was a series of 48 American nuclear tests conducted in 1964 and 1965. These followed the Niblick series and were in turn followed by Flintlock. All but one of these blasts were conducted beneath the Nevada Test Site.
A test may be either single or a salvo test. A salvo test consists in two or more explosions "where a period of time between successive individual explosions does not exceed 5 seconds and where the burial points of all explosive devices can be connected by segments of straight lines, each of them connecting two burial points and does not exceed 40 kilometers in length". It is therefore evident that the number of tests is not always the same as the number of devices tested.
The individual blasts were:

- An appended number represents a member of a salvo test. They usually all have the same name, like Tub-A, Tub-B, ..., but early on had separate names, so other members are denoted by "(with xyz)".
- Universal Time at the Nevada Test Site is 8 hours after local time; UT dates are one day after local date for UT times after 16:00.
- Universal Time in Mississippi is 6 hours after local time; UT dates are one day after local date for UT times after 18:00.
- Rough place name and a Lat/Lon reference. Some are extremely accurate; others (like airdrops and space blasts) may be quite inaccurate. Many have proforma rough locations, shared with others in that same area.
- Elevation is the ground level at the point directly below the explosion relative to sea level; height is the additional distance added or subtracted by tower, balloon, shaft, tunnel or other contrivance. For air bursts it is the absolute altitude of the explosion disregarding ground level (though the ground level is given for comparison), and for rockets the ground level is "N/A".
- Atmospheric, airdrop, balloon, gun, cruise missile, rocket, surface, tower, barge and cratering are all considered atmospheric in the PTBT. Sealed shaft and tunnel are underground.
- Include weapons development, weapon effects, safety test, transport safety test, war, science, joint verification and industrial/peaceful, which may be further broken down.
- Designations for test items where applicable, nicknames for individual bombs in quotes. US names are "Mark #" or "B#" for bombs, "W#" for rocket warheads, "X#" for experimental, plus names like "Piccolo". "Primary" refers to a test of only the primary (fission) stage of a multi-stage bomb.
- Estimated energy yield in tonnes, kilotonnes, and megatonnes (and yes, they are all metric units).
- Emissions to atmosphere, where known. No entry means unknown, probably none; otherwise notation for whether measured on the site only or off the site, and the maximum amount released, in Curies ("Ci") with metric prefixes.
