The frigates of the De Zeven Provinciën class have 2 important roles. They have a command role in facilitating the operations of the deployable and operational staff of the Royal Netherlands Navy, the Netherlands Maritime Force (NLMARFOR).
They are also equpped for air-defence tasks. They must be capable of providing protection for an entire fleet. The dual-role tasking is the reason that the ships are known as air-defence and command frigates.
The most striking characteristic of the air-defence and command frigates (LCF) is that they use stealth technology. That can be seen by the sharp lines and angular appearance. The high degree of automation of the ships' systems means that the LCFs, in spite of their large size, can be operated by a ship's company of 202 people, including staff.
The ships were built by the Royal Schelde Group, of Flushing, Netherlands. Spain and Germany also participated during the design stage.
