The US Navy has deployed a submarine capable of carrying up to 154 Tomahawk missiles to the Middle East in what appeared to be a show of force towards Iran following recent tensions.

The Navy rarely acknowledges the location or deployment of submarines and Timothy Hawkins, a spokesman for the 5th Fleet based in the Gulf nation of Bahrain, declined to comment on the submarine’s mission or what had prompted the deployment.

He said the nuclear-powered submarine, based out of Kings Bay, Georgia, passed through the Suez Canal on Friday.

“It is capable of carrying up to 154 Tomahawk land-attack cruise missiles and is deployed to US 5th Fleet to help ensure regional maritime security and stability,” Mr Hawkins said.

The 5th Fleet patrols the crucial Strait of Hormuz, the narrow mouth of the Persian Gulf through which 20% of all oil transits.

Its region includes the Bab el-Mandeb Strait off Yemen and the Red Sea stretching up to the Suez Canal, the Egyptian waterway linking the Middle East to the Mediterranean Sea.

The US, the UK and Israel have accused Iran of targeting oil tankers and commercial ships in recent years, allegations denied by Tehran.

The US Navy has also reported a series of tense encounters at sea with Iranian forces that it said were being recklessly aggressive.

Last month, the US launched air strikes against Iran-backed forces in Syria after a rocket attack killed a US contractor and wounded seven other Americans in that country’s north east.

Tomahawk cruise missiles launched from ships or submarines can hit targets up to 1,500 miles away. They were famously employed during the opening hours of the 2003 US-led invasion of Iraq and in response to a Syrian chemical weapons attack in 2018.

US-Iranian tensions have soared since then-president Donald Trump withdrew from a 2015 agreement with world powers that provided sanctions relief in return for Iran curbing its nuclear activities and placing them under enhanced surveillance.

The Biden administration’s efforts to restore the agreement hit a wall last year.

The tensions have worsened as Iran has supplied attack drones to Russian forces in Ukraine and as Israel and Iran have escalated their years-long shadow war in the Middle East.

In addition to drawing closer to Moscow, Tehran has sought improved relations with China, which brokered an agreement last month to restore diplomatic ties between Iran and Saudi Arabia.
