# Shayetet 7

Shayetet 7 is the only submarine flotilla of the Israeli Navy. It is based in Haifa naval base and operates Dolphin-class submarines. It was established in 1959 and is considered an elite unit due to the nature of its services.

## Nature of service

The service in the submarine fleet is difficult, challenging and often far from the country's borders, so the submarine crews have to be very cohesive. Another derivative of the great distance from the country's borders is that the submarine crew is operationally competent and ready for war at any time.
Every operational mission of the submarine has a military doctor and a medic on board who have undergone special training to treat the wounded, including dealing with a multi-casualty incidents, deep under the surface of the water. In the absence of an emergency, the doctor who joins any operational mission also carries an intelligence role for everything, in which he is engaged throughout the mission as one of the combatants.
The unit's objectives include
* Attacking enemy vessels
* Covert intelligence gathering
* Deployment and recovery of Shayetet 13 naval commandos
* Acting as a support unit for other units
* Believed to be part of the country's nuclear weapons capability.

## History
### Establishment

Two used S-class submarines were purchased from the Royal Navy . These submarines were built in World War II, and refurbished in England for the Israeli Navy. An Israeli team that went through a training period in France and the United Kingdom under British supervision was the crew for the first submarine. The flotilla was established on December 16, 1959, when INS Tanin (C-71) entered the port of Haifa. The second submarine, INS Rahav (C-73), arrived at the shores of Israel in July 1960.

### Six Day War

During the Six Day War, the flotilla participated in the Operation Alexandria in which Tanin led six fighters from Shayetet 13 into action in the port of Alexandria . While waiting to collect the divers, the submarine was attacked by an Egyptian vessel and damaged. The next day she returned to the meeting place to collect but the divers had already been captured by the Egyptians. Multiple civilian ships were destroyed in this operation.

### Arrival of T submarines

In 1965, Israel purchased three T-class submarines from the Royal Navy: Leviathan, Decker, and Dolphin. The T-class submarines were larger and more sophisticated than the S-class submarines, but they were also outdated submarines from the World War II period that had undergone a process of upgrade and renovation. The submarines arrived after the Six Day War.

### Sinking of INS Dakkar

A submarine of the flotilla, INS Dakkar, sunk on January 25, 1968, on its way from Britain to Israel and all 69 members of its crew perished. The remains of the submarine and the place where it sank were only discovered in 1999.

### Yom Kippur War

The flotilla did not take part in the Yom Kippur War due to maintenance issues.

### Introduction of Gal-class submarines

The Gal-class submarines entered the service in the flotilla in the late 1970s, these small but agile and sophisticated submarines were continuously upgraded with newer systems to maintain their technological edge. They were somewhat unusual in that all boats of the class were at equipped with six-tube retractable Blowpipe surface-to-air missile launchers controlled from inside the boat, though these were later removed.

### 1982 Lebanon War

The flotilla participated in the 1982 Lebanon War and carried out Operation Dreyfus which was a military operation to locate and identify enemy ships using submarines . In June 1982, during the operation, an Israeli Navy submarine hit a civilian ship carrying refugees, due to the suspicion that they were terrorists. 25 people were killed in the incident.

### Introduction of Dolphin-class submarines

Starting from 1999, the Dolphin-class submarines have continued to serve the Israeli Navy as a part of the flotilla and are expected to continue their service till 2030.

### Sudan airstrikes

In November–December 2011 two Israeli air raids against Gaza-bound weapon smugglers in Sudan were accompanied by Israeli submarine activity off the Sudanese coast.

### Syrian civil war

On July 5, 2013, during the Syrian civil war, an Israeli missile strike against the Syrian port of Latakia was made in coordination with the United States, with long-range missiles launched from a Dolphin-class submarine. The attack targeted newly unloaded Russian-made Yakhont long-range high-performance anti-ship missiles and associated radars.
