[3] At the time of the contract's award, the Mangusta was to be withdrawn from 2025, at which point the type is scheduled to have begun to be replaced by 48 AW249s, which are designated by the Italian military as the AH-249.

[4] Prior to the 2017 contract, the Italian Army and Leonardo had studied options for the future of the Mangusta, the service had rejected one proposal to replace the type with an attack-orientated variant of the AgustaWestland AW149 helicopter; instead, it opted for a series of low-risk upgrades and enhancements to be applied to the existing A129s to boost its endurance, situational awareness, and information-handling capabilities as medium-term measure.

[6] In July 2018, Leonardo and the Polish Armaments Group signed a letter of intent in regards to the collaborating on a bid to supply the AW249 to meet Poland's Kruk combat helicopter programme, and speculated on the use of its PZL-Świdnik subsidiary to locally produce elements of the rotorcraft.

[4] Amongst other abilities, the mission system will be capable of remotely operating unmanned aerial vehicles (UAV)s, and incorporate numerous situational awareness aids as to reduce pilot workload and increase safety.

[9] The AW249 is to be equipped with electro-optical countermeasures and other self-defence systems, such as the DIRCM (Direct InfraRed Counter Measures) ELT\577 QUIRIS and the ELT\162 radar warning receiver.

[13] Early on in development, two powerplants were considered for use on the AW249, the General Electric T700 and the Safran Aneto turboshaft engines, the latter having been recently selected for the commercial AgustaWestland AW189K.
