Liam Gibbons, aged 23, from Chemical Road, Morriston, and Ashley Heaven, aged 23, from Gwynfor Road, Cockett, got 3 years each for possession with intent to supply cocaine.
James Rand, aged 32, from Conway Road, Penlan, was sentenced to 4 years and 6 months for possession with intent to supply cocaine.
As part of the operation £7,000 of cocaine was seized and destroyed along with £3,000 of cash which has been forfeited.
Detective Inspector Marc Gardner of South Wales Police said: “These detentions will have a significant impact on disrupting the supply of drugs into the communities of Swansea.
“We recognise the harm that comes with the supply of drugs into an area, and we are committed to dealing with those responsible for such criminality.
“We hope these sentences send out a clear message that drug dealing will not be tolerated in South Wales, and we will do all we can to remove harmful drugs from our streets.
“We continue to encourage people to contact us with any information or concerns relating to drugs supply in their community.
