RAF Logistics - Summary - DEFENCE EQUIPMENT AND SUPPORT (DE&S), DEFENCE Infrastructure Organisation DIO


In parallel with the establishment of PJHQ at Northwood it became important to combine the separate logistics functions of the three Armed Services. As a result, in 2000 the three distinct separate service logistic functions were fused into one and the Defence Logistic Organisation was formed.

From 1 April 2007 the Defence Procurement Agency (DPA) and the Defence Logistic Organisation (DLO) were merged to form Defence Equipment and Support (DE&S).

DE&S has been described as ‘the engine’ that delivers ‘Through Life’ equipment and logistic support, and making sure the whole factory to front line process is seamless and properly integrated.

The Headquarters of DE&S is at Abbey Wood (Bristol) a site that is the largest MoD facility in the UK with a site workforce of about 10,000. DE&S is a Top Level Budget Holder and employs about 29,000 personnel (about 77 per cent civilian).


Over the next ten years, the UK Government plans to spend about £150 billion on new equipment and equipment support as follows:

Procurement of new equipment £60 billion
Support for new equipment entering service £18 billion
Support for existing in-service equipment (1) £68 billion
Contingency against risk £4.8 billion

(1) Includes spending on routine spares and maintenance, ship refits, support arrangements for our communications and information infrastructure, and the running costs of the nuclear propulsion and nuclear weapons production facilities.

Expenditure by service sectors over the next ten years is shown under the following headings:

Ships £17.4 billion
Submarines and Deterrent £35.8 billion
Combat Air £18.5 billion
Air Support £13.9 billion
Helicopters £12.1 billion
Information Systems and Services £15.7 billion
ISTAR £4.4 billion
Land Equipment £12.3 billion
Weapons £11.4 billion

In a normal year expect the MoD to spend about 40 per cent of its budget on equipment and equipment support.

Finances already allocated to equipment and equipment support over the period 2013 to 2017 are as follows:

Financial year 13/14 14/15 15/16  16/17
£ Billions 13.8 14.3 15.5 15.3

Some of the DE&S responsibilities to Joint Operations include:

Logistics planning, resource management, contractual support and policy
Global fleet management and land-based equipment
Support of the naval fleet and all naval systems
Communication and Information Systems
Transport and movements
Food and ration packs

Storage for all equipment and materiel

In 2013 the MoD announced that an assessment phase was in progress for a future DE&S business model based around a Government - Owned Contractor - Operated (GOCO) entity. If finally approved the GOCO would be implemented in stages.


Formed on 1 April 2011 and with a headquarters in Sutton Coldfield the DIO replaced the former Defence Estates organisation and brings together the majority of property and infrastructure functions from across the Ministry of Defence.

The DIO, a Top Level Budget Holder (TLB) has an annual expenditure of approximately £3.3 billion and assets worth over £20 billion. The overall area of the Defence Estate is estimated at being in the region of 2,400 sq kms.
