Hampshire will share in a £1.1 billion package of investment in military capabilities such as drones to be unveiled by David Cameron today.

Cash for the ''vital'' Ministry of Defence programmes has been found as a result of austerity measures and prudent financial management, the Prime Minister will say.

The funding pot includes an extra £800 million of investment in an intelligence, surveillance, target acquisition and reconnaissance package.

It will bolster special forces' ability to deal with the threat of global terrorism and hostage taking, according to No 10.

A further £300 million will be used for existing programmes, including unmanned aircraft and next generation radars for Typhoon combat jets.

During a visit to the Farnborough International Air Show, Mr Cameron will also outline plans to set up a UK Defence Solutions Centre in the Hampshire town to develop new defence technology.

A £4 million UK Centre for Maritime Intelligent Systems based in Portsmouth is also being launched as well as a ''defence apprenticeship trailblazer'' scheme to attract new graduates to the industry as well as develop a new masters level standard in advanced systems engineering.

Mr Cameron will say: ''Having modern, technologically advanced and flexible Armed Forces to protect us and our interests is vital.

''Because of the difficult decisions we have taken to tackle the deficit we are able to make these vital investments in our defence capabilities.

''We are also taking action to sustain our thriving defence industry, as part of our long-term economic plan to back business, create jobs and secure a brighter future for hard-working people.''
