# The armed forces: strength, recruitment and retention

The UK armed forces numbered 183,407 service personnel at 1 April 2026, 1,513 more than a year earlier and the first annual growth in over a decade. Recruitment now exceeds departures across the forces as a whole, though not in the Army. The measure that would say whether that is enough, the workforce requirement, has not been published since 1 April 2021.

## How to read this

These are the Ministry of Defence's own quarterly service personnel statistics, accredited official statistics counting people rather than posts. Strength is a stock at a single date; intake, outflow and applications are flows over the twelve months ending on the date shown, which is why the recruitment figures run a quarter behind the strength figures. Trained strength counts those who have passed phase 2 training, so it is smaller than total strength and is the figure MoD measured against its workforce requirement when it still published one. Nothing here measures capability, equipment or readiness: it is a headcount.

## 183,407 service personnel, growing for the first time in years

At 1 April 2026 the UK armed forces numbered 183,407 service personnel: 137,966 UK regulars, 4,464 Gurkhas and 32,034 volunteer reserves, alongside smaller categories of reserve and locally engaged staff. That is 1,513 more than a year earlier, a rise of about 0.8 per cent. MoD's own summary rounds these to 183,410 and 1,510.

| name | value |

| UK regular forces | 137,966 |
| Volunteer reserve | 32,034 |
| Gurkhas | 4,464 |

- **All personnel**: 183,407
- **Year change**: 1,513

## No one has published the target since 1 April 2021

Headcount alone cannot say whether the forces are big enough. The figure that could is the workforce requirement, the number of trained personnel the forces are meant to have, which MoD used to publish beside actual strength. At 1 April 2021 the requirement was 144,710 against a trained strength of 136,599, a shortfall of 8,111. MoD's note 11 states that following the Integrated Review and Spending Review the future workforce requirements “are not available after 1 April 2021”, and none has been published since. Trained strength has fallen a further 9,858 to 126,741 in the five years since. Whether that is a shortfall, and how large, is not a question these statistics can currently answer.

- **Last period**: 1 April 2021
- **Requirement**: 144,710
- **Trained then**: 136,599
- **Deficit then**: -8,111
- **Trained now**: 126,741
- **Fall since**: 9,858

## 14,370 joined, 13,393 left

Over the 12 months to 31 March 2026, 14,370 people joined the UK regular forces and 13,393 left, a net gain of 977. Of those who left, 6,061 were trained personnel leaving voluntarily, which is the outflow the forces have least control over and the one recruitment has to replace. The balance differs sharply by service.

**Tri**: start 136,998, intake 14,370, outflow 13,393, end 137,966, net 977

- **Voluntary**: 6,061
**Services**

| name | start | intake | outflow | end | net |

| Royal Air Force | 30,450 | 2,767 | 2,208 | 31,082 | 559 |

## Fewer people are choosing to leave

The turnaround owes as much to retention as to recruitment. Across the 12 months to 31 March 2026 the outflow rate for trained personnel was 8.2 per cent, down from 9.6 per cent a year earlier, and the voluntary outflow rate fell from 5.9 to 5.0 per cent. A single percentage point of voluntary outflow is worth roughly 1,270.0 trained people a year, so a fall of this size does more for strength than a comparable rise in recruitment would.

- **Outflow**: 8.2
- **Outflow prev**: 9.6
- **Voluntary**: 5
- **Voluntary prev**: 5.9

## Applications are up overall and down sharply in the Army

Applications are the earliest signal of whether recruitment can be sustained, and they run a quarter behind the strength figures. In the 12 months to 31 December 2025 the services received 252,160 applications between them, against 278,010 the year before. The direction is not shared: the Naval Service and Royal Air Force both rose substantially while Army applications fell by about 26 per cent, even though the Army receives far more applications than the other two services combined.

| name | value | prev | changePct |
|---|---|---|---|
| Royal Navy and Royal Marines | 43,491 | 29,669 | 47 |
| Army | 147,410 | 198,537 | -26 |
| Royal Air Force | 61,259 | 49,804 | 23 |

- **Total**: 252,160
- **Prev total**: 278,010

## 55,351 civil servants alongside 148,779 service personnel

Defence headcount is not only uniformed. At 1 April 2026 the Ministry of Defence employed 204,130 people in total: 148,779 service personnel and 55,351 civil servants on a full time equivalent basis, about 27 per cent of the department. Civil servants here exclude trading funds and locally engaged civilians abroad, and the two groups are counted on different bases, so the split is a rough guide to the shape of the department rather than a precise ratio.

- **Total**: 204,130
- **Service**: 148,779
- **Civil**: 55,351

## What this page can and cannot tell you

**Are the armed forces undermanned?**

These statistics cannot say. The workforce requirement that would answer it has not been published since 1 April 2021, when trained strength was 8,111 below it. Trained strength has fallen further since, but comparing today's strength against a five year old requirement would assume the requirement never changed, and the Integrated Review that ended its publication was itself a decision to change the shape of the forces.

**Is the recruitment crisis over?**

One year is not a trend, and the improvement is uneven. Intake exceeded outflow across the forces as a whole for the first time in years, but the Army, which is the largest service and has the deepest shortfall, was close to flat, and Army applications fell about 26 per cent over the year. Much of the gain came from people choosing not to leave rather than from more people joining.

**Does headcount measure military capability?**

No. This is a count of people, not of ships, aircraft, munitions, readiness or the ability to sustain an operation. A force can grow in numbers while losing capability, or hold numbers while losing experience, because these figures do not distinguish a newly trained recruit from a departing specialist with twenty years of service.

**Why do the recruitment figures cover a different period?**

Strength is measured at a single date, 1 April 2026. Intake, outflow and applications are twelve month flows, and MoD publishes applications a quarter further behind than the rest, so they cover the 12 months to 31 December 2025. The periods are stated on every figure here rather than being blended into one date.

## Caveats and data notes

- Strength figures are a stock at 1 April 2026. Intake, outflow and outflow rates cover the 12 months to 31 March 2026, and applications cover the 12 months to 31 December 2025, because MoD publishes the recruitment pipeline a quarter further behind. Each figure on this page states its own period.
- The workforce requirement is not published after 1 April 2021. MoD's note 11 attributes this to the Integrated Review and Spending Review. This page reports the last measured gap and does not carry that requirement forward, because doing so would assume five years of unchanged defence planning.
- Trained strength counts personnel who have passed phase 2 training, and for the Army trade training, so it is smaller than total strength. It is the basis MoD used against the workforce requirement.
- These are headcounts of people, not full time equivalents, except for MoD civil servants which are full time equivalent. The two are not directly comparable.
- Nothing here measures capability, equipment, readiness or experience. A headcount cannot distinguish a recruit from a departing specialist.
- Figures are for the UK armed forces as a whole. This page does not break them down by nation or region, and MoD does not publish service personnel strength on that basis in this release.
