American Liberty Ship.
The RICHARD MONTGOMERY, also known as the Wreck or the Bomb Ship, sits in the Thames Estuary one and a half miles from Sheerness and five miles from Southend  with its masts visible at all states of the tide.

To this day, a massive 5,348 tons of bombs remain on the Richard Montgomery.

Watch this short video about the Richard Montgomery.

The Richard Montgomery is a Liberty Ship and as such played an important part in World War Two by transporting large amounts of materials and war supplies to Britain and by so doing helping to win the war.

Today the wreck of the Richard Montgomery lies on the seabed, with its masts above the surface, off Sheerness, the Isle of Sheppey, Kent, England.

In this BBC photograph of the Richard Montgomery sinking. It is not difficult to see why the two holds at the stern, Cargo Holds 4 and 5, were off-loaded while the munitions in holds 1, 2, and 3 at the front of the ship were abandoned.


​When the Montgomery run aground and broke her back on the 20th August 1944, she carried in holds  6,862 tons of bombs. This is a record of the bombs which were removed during the Salvage operation.

Total 1514 tons of munitions and miscellaneous nonexplosive parts were removed from the Richard Montgomery. Richard Montgomery was loaded with 6862 tons of munitions.

Their remains a MASSIVE 5,348 tons of munitions on the Richard Montgomery.

25th July 1944. The Richard Montgomery, with 120 merchant ships and 33 escorts in Convoy HX 301, left New York bound for the D-day landing beaches. Her cargo is listed as 6,862 tons of Explosives and Ammunition.

On arriving in British waters, the Richard Montgomery continued on her journey around the top of Scotland and down the east coast of England as part of convoy FS 1543, arriving in the Thames Estuary. 

20th August 1944. Incorrectly positioned by the Southend Harbour Master in a crowded anchorage the Richard Montgomery dragged her anchor and irretrievably grounded, despite other close by ships sounding their horns in warning.

Three days after the Montgomery ran aground the salvage ships “Empire Nutfield and SS “Flathouse” arrived with three gangs of stevedores and began to unload her deadly cargo. The Tug “Atlantic Cock” supplied steam for the derricks.

4th September the strong winds and high waves forced the salvage operations to be abandoned. The weather had won the battle for the Montgomery.

Between the 23rd August and the 4 September 1944, 1,514 tons of bombs were removed from the Richard Montgomery. 

6,862 tons of bombs were on the Montgomery when she grounded. 1,514 tons of bombs were removed in the salvage operation. 5,348 tons of bombs remain on the Richard Montgomery.

In an attempt to play down the gravity of thousands of tons of deteriorating bombs, in close proximity to populated areas, the Maritime and Coastguard Agency wrongly state that 1,400 tons of explosive material (or TNT) ​remain on the Montgomery.  (During WW2 a typical general-purpose bomb was 50% casing weight and 50% explosive material. Therefore, the explosive material or TNT on board the Montgomery is not 1,400 tons of TNT, but almost twice that at 2,674 tons of TNT.)

The figures clearly show that 5,348 tons of bombs remain on the Montgomery.

The Richard Montgomery was built in Florida at the St. Johns River Shipbuilding Company and was launched on the 15 June 1943 and sunk on the 20 August 1944.

Liberty Ships, including the Richard Montgomery, were built to the same basic design which is as follows:

Length:  441 feet, 6 inches.  Beam:  57 feet.  Draft:  27 feet, 9 inches 

Displacement: 14,245 tons (fully loaded) Gross: (weight) 7,176 tons. (7,176 tons is sometimes mistakenly given as the weight of the cargo and not the weight of the ship.)

Cargo Capacity:  9,140 tons, nominal (over 10,000 tons, with external deck cargo) 

Propulsion:   Two oil-fired boilers. One triple expansion 2,500 HP steam engine.

Speed: 11.5 knots.

Range: 17,000 Nautical Miles.

Armament: One 3-inch bow gun, one 5-inch stern gun and six to eight 20 mm guns.

Typical Crew Size: Up to 44 Merchant Mariners and 12 to 25 Naval Armed Guard.

SS Richard Montgomery

It should be remembered that the Richard Montgomery, like other Liberty ships played a vital role during World War Two. The Richard Montgomery was not a British Ship; it was an American Ship. It wasn’t bringing munitions for the British Army, it was transporting them to Normandy, shortly after D-Day, for the American armed forces.

Liberty ships were built cheaply and quickly to last the duration of the war. They were assembled in production line fashion, to meet a need in a time of dire emergency. They were built to replace the millions of tons of shipping which had been sunk by German U-boats in the Atlantic and to give more capacity to build up armaments and munitions approaching D-day (the Invasion of German controlled Europe by Great Britain and the Commonwealth and the United States of America.)

Liberty Ships had one failing, which at first went unrecognized. The steel used to build them was of a low grade and cold weather such as that found in the North Atlantic made the steel brittle and prone to cracking. On a ship built of steel plates riveted together, this wasn’t a problem as the crack would only travel as far as the edge of the plate. On welded ships there was nothing to stop the crack which got longer and longer. These crack would often start at weak points such as the corners of Hold openings. (Now you know why airline windows aren’t square but have rounded corners.)

The SS Richard Montgomery was named after General Richard Montgomery.  Having first served in the British Army, during the American War of Independence, he joined the American Continental Army to fight against the British. He was killed on the 31st December 1775 at the siege of Quebec.
