The Chancellor has delivered the Budget, with defence featuring as he spoke to the House of Commons.
A pledge of £1 billion for the Ministry of Defence (MOD) has been labelled as a "drop in the ocean" compared to what is needed, by former Royal Navy chief, Admiral Lord West.
The Labour peer said that the cash - although welcome - "will not stop the hollowing out" of Britain's armed forces.
Here is what the Budget announcement means for defence, in numbers:
£1 Billion In 'Additional' Funding
Philip Hammond has pledged an extra £1 billion which he says will "boost our cyber capabilities and our anti-submarine capabilities and to maintain the pace of the Dreadnought programme to ensure a continuous at sea deterrent".
A senior Royal Navy officer recently said he is "extremely" confident HMS Queen Elizabeth would be able to fend off a cyber attack, while the UK and US announced a joint accord against cyber threats.
Earlier this year, the Prime Minister announced an extra £600 million to keep the Dreadnought programme on schedule.

£70 Million For The DNRC
Up to £70 million has been pledged to construct the national element of the Defence and National Rehabilitation Centre (DNRC) near Loughborough.
The new facility was formally gifted to the nation by the Duke of Cambridge in June, with the old site at Headley Court closing.
£10 Million Donation To Support Veterans
Also announced on Monday was that the Treasury is to make a £10 million donation to mark the Centenary of the Armistice by supporting veterans with mental health needs.
"Many projects are raising money for veterans charities from sales of commemorative items on which VAT is charged," said the Chancellor.
"We cannot waive the VAT due on these sales, but we can make a donation with the VAT we will receive.
"The Treasury will mark the centenary of the Armistice by making a donation of £10 million to the Armed Forces Covenant Trust to support veterans with mental health needs."
£1.7 Million For Educational Programmes
The Chancellor confirmed that £1.7 million will be spent on educational programmes in schools to mark the 75th anniversary of the liberation of concentration camps.
