Admiral Kasatonov Calculated One Atomic Torpedo to Sink a US Carrier

By Roy Castellano · August 19, 2026

Kept secret until June 2017, a Soviet tactical guide envisioned the annihilation of NATO carrier groups with single nuclear torpedoes and orbital surveillance.

A single atomic torpedo detonating within a calculated semicircle would have erased thousands of American sailors in a heartbeat. For the men aboard the 6th Fleet in the Mediterranean, the cost of a Soviet miscalculation was not a battle, but a sudden, absolute erasure.

On May 15, 1962, Richard Helms, then Deputy Director of Plans, sent a memorandum to the Director of Central Intelligence. The enclosure was a verbatim translation of an article titled "On the Problem of the Tasks of the Navy and Methods for Accomplishing Them," written by Admiral V. Kasatonov. The text had appeared in the October 1961 issue of Voyennaya Mysl (Military Thought), a journal published by the USSR Ministry of Defense. According to the memo, this specific version was part of a "Special Collection" classified TOP SECRET by the Soviets and distributed only down to the level of Army Commander.

The 1000 Kilometer Maneuver

Kasatonov used the article to settle a tactical dispute with another officer, Admiral V. Platonov. At the heart of the disagreement was the vulnerability of the American carrier strike group. Platonov had expressed doubt that these units would operate primarily on the open sea, but Kasatonov viewed that doubt as baseless. He noted that NATO commanders recognized that ground airfields and missile sites could be "reconnoitered even before the beginning of combat operations and subjected to powerful strikes by nuclear missiles in the initial hours and minutes of a war."

To Kasatonov, the carrier was the only reliable nuclear delivery platform because of its mobility. He claimed carrier groups were capable of performing a maneuver of "1000 km in one calendar day in any direction," making them less vulnerable to shore-based missile strikes. The record notes that the Soviets had been monitoring NATO exercises in the Norwegian Sea and the Mediterranean, observing how the 6th Fleet utilized radio silence and vast distances to mask its intent.

One Atomic Torpedo

While the carrier was maneuverable, Kasatonov argued it was far from invincible. He dismissed Platonov's negative evaluation of atomic torpedoes, framing them as the ultimate solution to the problem of the carrier strike group. The arithmetic of the kill-chain was brutal and precise. Kasatonov wrote that to destroy a strike aircraft carrier with conventional weapons, a submarine would need to hit it with "no less than 8 to 10 torpedoes."

An atomic torpedo changed the probability of success. Because the weapon did not require a direct hit—only a strike within a "semicircle with a sizable radius"—the probability of destroying the target, in Kasatonov's view, "increases greatly and in several instances approaches one."

This shift in lethality offered a strategic multiplier. By replacing conventional charges with atomic ones, a single submarine could increase its "self-sufficiency in ammunition" by four times, as a single torpedo could replace a four-torpedo salvo. The record shows a chilling confidence in the ability of atomic submarines to intercept these groups on the ocean lanes used to reach distant bases.

Transports and Troops

Kasatonov's vision for a naval war extended beyond the carriers to the very fringes of the atmosphere. He suggested that the struggle against missile-carrying submarines should include "orbital means of combat which are based on the use of artificial earth satellites." These satellites, combined with "atomic aircraft" capable of long flights at low altitudes, were intended to create a net of detection and destruction that no NATO vessel could evade.

However, the most telling part of the record is Kasatonov's disagreement with Platonov regarding the primary objective of a war. Platonov had suggested that the Navy should prioritize the destruction of aircraft carriers. Kasatonov disagreed, arguing that this was an "overestimation" of the enemy's ability to defend its convoys.

He asserted that a considerable number of transports would follow ocean lanes without carrier cover. While he admitted that a commander should prefer a carrier over a transport if given the choice, the overarching mission remained the disruption of shipping. In the Soviet view, the primary targets for strikes remained the transports carrying troops and cargo.

Much of the memo is obscured by redactions marked "1.3(a)(4)," leaving the specific identities of the "reliable, direct" sources who procured the journal blacked out. The record ends with the cold logic of the Soviet naval staff: the war would be won not just by sinking the warships, but by destroying the tonnage of the transports.
