F125 is the project name for the Type 125 class of frigates, currently in development for the German Navy by ARGE F125, a joint-venture of Thyssen-Krupp and Lürssen. F125 is officially classified as frigates but in size and role they could be classified as destroyers.

In contrast to the Bremen class, which has been built with cold war scenarios in mind, the F125 will have much enhanced land-attack capabilities. This which will better suit frigates in possible future peacekeeping and peacemaking missions. For such reasons, the F125 will also mount non-lethal weapons.

Major design goals are reduced radar, infrared and acoustic signatures (stealth technology), something that was introduced to the German Navy with the Sachsen class frigate and was further developed with the Braunschweig class corvette, the first ship nearing completion.

Other important requirements are long maintenance periods: It should be able to deploy F125 class frigates for up to two years away from homeports with an average sea operation time of more than 5000 hours per year (that's nearly 60%). For this reason, a combined diesel-electric and gas arrangement has been chosen for the machinery. This allows the replacement of large and powerful diesel engines for propulsion and sets of smaller diesel generators for electric power generation with a pool of med-sized diesel generators, reducing the number of different engines.

To enhance survivability of the frigates, important systems are laid out in the two island principle, i.e. present at least twice at different places within the ship. This is also visible in the superstructures, which are split in two larger pyramidal deck houses. The arials of the phased array radar will be distributed over the two pyramids. This does not only ensure, the ships remains operational in case of larger damage because of accidents or enemy action, it also allows F125 frigates to keep station if needed when something breaks down and no replacement is available.

An initial batch of 4 frigates was ordered by the German Navy. Those will replace 4 out of 8 Bremen class frigates. The other 4 Bremen class frigates will probably be replaced by the second batch.

The initial batch of 4 ships costs around 2.2 billion Euros.
