Extremely small (as small as 5 inches (12.7 cm) diameter and 24.4 inches (62 cm) long) linear implosion type weapons, which might conceivably fit in a large briefcase or typical suitcase, have been tested, but the lightest of those are nearly 100 pounds (45.4 kg) and had a maximum yield

Suitcase nuclear weapons

There has been no official information released on the existence of true suitcase or briefcase-sized nuclear weapons in either the U.S. or Russian arsenals. However, the Washington, D.C.–based intelligence-firm, Center For Defense Information (CDI), states that the US government produced a class of nuclear devices in the late 1970s which were small enough to fit into an actual suitcase or briefcase. Likewise, CDI claims that a detailed training replica—with dummy explosives and no fissionable material—was routinely concealed inside a briefcase and hand-carried on domestic airline flights in the early 1980s.

 claimed that such Russian-made devices do exist and described them in more detail. These devices, "identified as RA-115s (or RA-115-01s for submersible weapons)" weigh from fifty to sixty pounds. They can last for many years if wired to an electric source. In case there is a loss of power, there is a battery backup. If the battery runs low, the weapon has a transmitter that sends a coded message—either by satellite or directly to a GRU post at a Russian embassy or consulate.” According to Lunev, the number of "missing" nuclear devices (as found by General Lebed) "is almost identical to the number of strategic targets upon which those bombs would be used."

Lunev suggested that suitcase nukes might be already deployed by the GRU operatives at the US soil to assassinate US leaders in the event of war. He alleged that arms caches were hidden by the KGB in many countries for the planned terrorism acts. They were booby-trapped with "Lightning" explosive devices
