Defence Training Estate is an organisation within the United Kingdom Ministry of Defence. It is the operating division of the Defence Infrastructure Organisation, and is responsible for the management of the 78% of the MoD's estate allocated as Training Areas and Ranges. It provides sufficient and suitable estate to support the training requirements of the British Armed Forces, whilst ensuring environmental management and appropriate historical and archaeological preservation.

The organisation is headquartered at Waterloo Lines, Warminster,^[1] and has a number of regional headquarters responsible for the management of the training estate on a regional basis.

DTE works with nature conservation bodies to safeguard designated sites and protected species within the estate. These bodies include the Joint Nature Conservation Committee, Natural England, Scottish Natural Heritage, the Countryside Council for Wales and the Northern Ireland Environment Agency.^[2]

Some practical support is outsourced to Landmarc Solutions, a joint venture between Interserve (a UK support services company) and PAE (an American multinational support services company owned by Lindsay Goldberg).^[3][4]

DTE runs five Air Weapons Ranges for military operational training: RAF Holbeach and RAF Donna Nook in Lincolnshire (England), RAF Pembrey in Carmarthenshire (Wales), the Tain Air Weapons Range in Rossshire and Cape Wrath in Sutherland (Scotland). A former air weapons range at RAF Wainfleet in Lincolnshire was decommissioned in 2009. It had been in use since 1890 for artillery training, originally by the 1st Lincolnshire Artillery Volunteers.^[5]

DTE operate a principle of presumption of public access to the training estate. Access is limited where training and exercise activities are taking place or where the use of munitions precludes safe access.^[6]

As much of the training estate remains undeveloped, either through habitation or agriculture, the training estate holds considerable conservation and archaeological value.^[7]
