The UK Government's new National Cyber Force (NCF) will be located in Samlesbury in the North West, Defence Secretary Ben Wallace has confirmed.
Samlesbury is also home to a BAE Systems site.
The NCF draws together personnel from intelligence, cyber and security agency GCHQ, the Ministry of Defence (MOD), the Secret Intelligence Service (MI6) and the Defence Science and Technology Laboratory (Dstl), under one unified command for the first time.
Offensive cyber operations are those which can disrupt hostile state activities, terrorists and criminals threatening the UK's national security – from countering terror plots to conducting military operations.
The National Cyber Force was announced by Prime Minister Boris Johnson as part of the Integrated Review earlier this year.
Defence Secretary Ben Wallace said the National Cyber Force will bring highly skilled jobs to Lancashire and "embrace exciting new offensive cyber technologies".
"I am hugely proud and enthusiastic to see this happen, not only will it provide a catalyst for investment, but also see our levelling up agenda bring economic stimulus and tangible benefits to this region," he said.
GCHQ already has an office in Manchester, Europe's fastest-growing major tech cluster and, in 2018, Director GCHQ revealed how the organisation had degraded ISIS propaganda networks through cyber operations.
Foreign Secretary Liz Truss added that the NCF will "help confront aggressive behaviour from malign actors, and demonstrate that Britain is investing in next-generation defence capability to protect our people and help our friends counter cyber threats".
"It sends a powerful message to our allies and adversaries alike."
