The teams leading the fight against organised criminal gangs in Merseyside are being brought under the same roof for the first time.
More than a thousand staff will work at the operational command headquarters.
Built in Speke at a cost of £48million, it will be officially opened later.
Two rooms within the new centre have been named in honour of police officers who have been killed in the line of duty.
PC Phillips died in Wallasey while attempting to stop a stolen car in the early hours of 5th October 2015. More than 34 years earlier. PC Raymond Davenport was killed as he tried to stop a stolen car on Roe Street in Liverpool on July 4th, 1981.
Merseyside's Police Commissioner Jane Kennedy said the new centre brings the officers and staff who make up the Matrix team under one roof in a purpose-built centre.
