The function of the Alliance is to conduct a wide range of acoustic, oceanographic research and engineering technology tasks on behalf of NATO, Marina Militare and third party organizations when 'on hire' for charters in global waters. The design and construction of the vessel was done to create a versatile research platform that is adaptable to the Centre's needs and reduce noise output to the lowest possible level in order to minimize interference with research work.
Commissioned on 15 April 1988 to SACLANT (Undersea Research Centre – SACLANTCEN, then named NATO Underwater Research Centre – NURC and now CMRE – Centre for Maritime Research and Experimentation) of La Spezia, under the German flag.
Alliance was transferred to the Italian naval flag on 9 April 2016. The vessel is crewed and operated on behalf of NATO by the Marina Militare under a Memorandum of Understanding signed on 22 December 2015.[5]
It took part in Nordic Recognized Environmental Picture research mission, a multi-year oceanographic research project that started in 2017 and has been conducted in different parts of the Arctic Ocean. The mission assess the impact of climate change in the Arctic, in particular, how the transformation of the Arctic affects sonar performance.[6]

There are two independent systems for ship communications and for scientific trials (with some overlap). The ship system, which uses radios complying with SOLAS and GMDSS rules, includes Inmarsat systems (e-mail, fax and phone).
