The Cuban Missile Crisis establishes the ‘hotline’

“Get Premier Kissov on the hotline,” said US President Merkin Muffley during the 1964 movie, “Dr. Strangelove.”

Muffley is using the direct telephone hotline connection with the Russian premier in hopes of avoiding nuclear war.

An earlier scene in the movie mentions the infamous “red phone.”

The US president’s hotline telephone was specifically highlighted during scenes in the 1964 movie, “Fail Safe.” Although the movie was filmed in black-and-white, I assume the hotline phone was red.

Come to think of it, the 1960s television series, “Batman,” featured a red Bat Phone with a direct hotline to Commissioner Gordon’s office.

And so, the hotline became thought of as a red telephone sitting on the desks of the US president and Russian Soviet leader. An immediate connection between the two occurred whenever the handset of either phone was lifted.

Well, that’s not quite how it worked.

The hotline was not a red telephone, but a teletype printer. There was one inside the US Pentagon, and one inside Russia’s Kremlin.

Due to the lengthy amount of time required to send, receive, and decipher messages with the Russian premier during the Cuban missile crisis in October 1962, both countries came very close to having a nuclear confrontation, which would have resulted in massive devastation and an enormous loss of life.

There were plenty of atomic missiles around during October 1962; the US nuclear warhead total was 3,500, while the Russian stockpile had about 580.

Fortunately, cooler heads prevailed, and the Cuban Missile Crisis ended without nuclear missiles being used.

Talks then began in earnest about implementing a direct communication link; a hotline between the two superpowers. This hotline would be used to reduce the risk of nuclear war because of delayed communications.

June 20, 1963, the US and Russia signed the “Memorandum of Understanding between the United States of America and the Union of Soviet Socialist Republics Regarding the Establishment of a Direct Communications Link.”

The memorandum understanding became known as the hotline agreement.

“For use in time of emergency, the Government of the United States of America and the Government of the Union of Soviet Socialist Republics [USSR] have agreed to establish as soon as technically feasible a direct communications link between the two Governments,” the memorandum began.

Ensuring the continued operation of the communications link and rapid delivery of any messages received over it would be the responsibility of each government.

Some of the technical specifics of the 1963 hotline agreement included:

• Telegraph-teleprinter equipment used for exchanging communications.

• One uninterrupted duplex wire telegraph circuit route connecting Washington to Moscow via London-Copenhagen-Stockholm-Helsinki for message transmissions.

• One full-time duplex radiotelegraph circuit routed from Washington to Tangier to Moscow, which shall be used for service communications and for coordination of operations.

Some of the equipment installed inside the Pentagon for the Washington hotline was provided by the Russian company, Avtomatika Concern. This equipment was tested and approved by US specialists.

American communications equipment was also installed inside the Kremlin for the Moscow end of the hotline.

If a US president wanted to quickly contact the Soviet premier/leader, they would call the Pentagon (by phone) with the message to be sent over the hotline to Moscow.

Both the US and Russia encrypted text messages using an ETCRRM (Electronic Teleprinter Cryptographic Regenerative Repeater Mixer) cipher machine built in Norway.

The physical path used for a hotline between the US and Russia was the TAT-1 (Transatlantic No. 1) submarine copper coaxial cable system. TAT-1 consisted of two individually amplified cables; one for transmitting and one for receiving.

The two cables, totaling 4,000 miles, were placed 3.7 miles beneath the Atlantic Ocean. TAT-1 became operational Sept. 25, 1956.

In the event the physical cable between the two countries was disrupted, the dedicated radio circuit between Washington and Moscow using a radio relay station in the city of Tangier, located in northwestern Morocco, would be used for message exchanges.

Aug. 30, 1963, the first test message was sent over the hotline from Washington to Moscow: “The quick brown fox jumped over the lazy dog’s back 1234567890.”

Rumor has it the Russians responded with “What does it mean when your people say the quick brown fox jumped over the lazy dog?

The hotline was first used by President Lyndon Johnson in 1967, to inform Russia of the US Naval fleet movements in the Mediterranean region during the Middle East Six-Day War.

President Richard Nixon used the hotline in 1971 and 1973.

The hotline agreement was updated in 1971, to provide the addition of two satellite circuits, which became fully-operational in 1978, the same year the TAT-1 cable was retired. The physical path of the hotline was transferred to a transatlantic fiber optic cable.

By 1980, Norway’s ETCRRM cipher machines were replaced by the Siemens M-190.

In 1986, high-speed facsimile (fax) telecopy machines were added to the “hotline.” They could be used to send typed messages, maps, charts, and drawings.

Since 2008, a dedicated computer network links Washington and Moscow for sending and receiving email, and instant messaging chat.

Oct. 31, 2016, President Obama used the hotline’s secure satellite connection to send a message to Russian President Vladimir Putin about his concerns with computer cyber hackers disrupting the upcoming US election.

“This age of fast-moving events requires quick, dependable communication in time of emergency,” President John F. Kennedy said June 20, 1963. He added, the hotline agreement was a “first step to help reduce the risk of war occurring by accident or miscalculation.”

The Memorandum of Understanding has been active for 56 years and, so far, there has been no nuclear exchange between the US and Russia.

It seems having a hotline keeps things from boiling over.
