HMS Antelope 23–24 May 1982: Complete Field Guide — Unexploded Bombs, EOD & the Loss of F170
23–24 May 1982. HMS Antelope survived the Argentine air attack that hit her. She was lost hours later because one of the bombs did not explode on impact.
That contradiction is what makes the story so important. Two bombs penetrated the Type 21 frigate without detonating. What looked at first like good fortune became an explosive-ordnance-disposal problem inside a damaged warship.
During the attempt to render one bomb safe, it detonated. Staff Sergeant James Prescott of 49 EOD Squadron Royal Engineers was killed and Warrant Officer Class 2 John Phillips was badly injured. Fire spread to the magazines. The ship was abandoned and broke apart the next day.
At a glance
- Date hit: 23 May 1982.
- Ship: HMS Antelope (F170), Type 21 frigate.
- Location: San Carlos Water.
- Attacker: Argentine A-4 Skyhawks.
- Bombs aboard: two unexploded bombs after the air attack.
- EOD team: Staff Sergeant James Prescott and WO2 John Phillips, 49 EOD Squadron Royal Engineers.

- Result: bomb detonated during EOD work; fires reached magazines; ship abandoned and sank/broke up on 24 May.
The unexploded-bomb problem at San Carlos
Argentine pilots repeatedly hit British ships during the San Carlos battle, but many bombs failed to explode.
That saved ships in the immediate moment. It also left crews with live bombs buried inside machinery spaces, magazines and structural debris.
The fuze problem was tied to the attack profile. Argentine aircraft flew extremely low to survive British air defences. A conventional bomb released only seconds before impact had little time to arm. Longer delays protected following aircraft from the blast of bombs dropped ahead of them, but could further complicate reliable functioning after a low release.
For British sailors, the result could be a 1,000lb bomb sitting inside the ship.
23 May: Antelope is hit
Antelope was operating as part of the force protecting the San Carlos anchorage when Argentine Skyhawks attacked.
Two bombs entered the frigate and failed to detonate. The ship remained afloat, but she now carried two large unexploded weapons in damaged compartments.
It was not possible simply to tow the ship away and ignore them. The bombs posed a continuing risk to the crew, nearby ships and the wider anchorage.
The EOD team
Staff Sergeant James Prescott and WO2 John Phillips of 49 EOD Squadron had already dealt with unexploded ordnance aboard HMS Argonaut.
The Royal Engineers Association records that on 22 May the pair rendered safe a bomb in Argonaut's boiler-room area under extremely cramped conditions, allowing repairs to proceed.
On 23 May they were sent to Antelope.
The first bomb
Access was difficult because of debris and damage. The team worked inside a warship that had already been penetrated by bombs and whose internal spaces had never been designed to give bomb-disposal technicians clean working room around an embedded weapon.
The exact problem was not merely “remove the fuze.” The bomb had to be approached without movement that might set it off, its damaged fuze understood and then neutralised using equipment adapted to the space available.

The more dangerous bomb
The second bomb had a damaged fuze and was judged more dangerous.
Prescott and Phillips made repeated attempts to remove the fuze remotely. According to the Royal Engineers Association account, three attempts failed.
On a fourth attempt, using different equipment, the bomb detonated.
The explosion
Staff Sergeant Prescott was killed instantly. WO2 Phillips was seriously injured.
A blast route had been prepared by opening doors and hatches through the ship, but the detonation was still powerful enough to tear through the compartment and ignite major fires.
The explosion then triggered further detonations and fire spread toward Antelope's magazines.
The image that went around the world
The burning frigate became one of the defining visual images of the Falklands War. Television cameras recorded the night sky lit by explosions as the ship burned inside San Carlos Water.
Those images can make the loss appear sudden. In reality, the ship's destruction was the end of a chain that began hours earlier with two bombs that had failed to explode.
The two dead
The official casualty tables record one Royal Navy and one Army death associated with HMS Antelope.
Prescott received the Conspicuous Gallantry Medal posthumously. Phillips received the Distinguished Service Cross.
The awards reflect the nature of the task: deliberately working on a damaged high-explosive bomb inside a warship because leaving it untouched was itself dangerous.

Why the ship was abandoned
Once the bomb exploded and fires spread, the danger was no longer local. Ammunition and fuel meant the crew could not safely contain the casualty.
Antelope was evacuated as internal explosions continued.
On 24 May the damaged hull finally broke apart and sank.
What Antelope teaches about unexploded bombs
“The bomb didn't go off” sounds like a lucky outcome. In naval warfare it can be the beginning of another battle.
An unexploded weapon creates three simultaneous problems:
- the ship may need to keep fighting while a live bomb remains aboard;
- repairs and movement can disturb the weapon;
- render-safe work may have to be carried out in cramped, damaged, hot or flooded compartments.
The EOD team has to operate close to the weapon precisely because everyone else needs distance from it.
Argentine bomb fuzes and British survival
Many British ships escaped destruction because Argentine bombs failed to detonate. The temptation is to treat that as simple incompetence.
The evidence is more useful than the insult. The attack method demanded very low release to survive the British defensive screen. That created a technical fuze problem. The Argentines continued working on it during the campaign, and later attacks showed that correctly functioning bombs could be devastating.

Ardent, Antelope and the cost of the beachhead
HMS Ardent had been lost two days earlier. Antelope followed. HMS Coventry and Atlantic Conveyor would be lost on 25 May.
Those losses were not random events around the edge of Operation Sutton. They were the cost of holding a fleet inside Argentine strike range while the land force established itself ashore.
The Iron Standard conclusion
HMS Antelope is the sharpest example in the Falklands of the danger posed by ordnance that fails to function as designed.
The Argentine bomb that did not explode on impact still destroyed the ship. It simply did so later, while two men were trying to make it safe.
That changes how the phrase “unexploded bomb” should be read. It does not mean harmless. It means the weapon has postponed the decision about when — and around whom — its explosive energy will be released.
