The unique Wärtsilä axial jet technology was a decisive factor in the award of this order because its characteristics - low noise, ease of maintainability, agile manoeuvring, and rapid acceleration and docking - perfectly fit the requirements for missions involving the JHSV.
These ships will support the US Navy, Marine Corps, and Army with the intra-theatre manoeuvres of personnel, supplies and equipment, and will provide fast disaster relief capabilities.
