Naval operations rely increasingly on flexibility by deploying small craft from large platforms, which is done for a number of reasons. Firstly, a large platform features more favourable motions in a seaway. Secondly, specialist performance, e.g. a high interception speed, is only required for the craft, with obvious cost benefits. Thirdly, replacing the legacy craft with a state-of-the-art craft enables easy upgrading. And fourthly, providing a relevant combination of craft allows tailoring of the capabilities the platform needs for its mission. Operations impacted by these developments include maritime security operations, often involving deploying small fast manned or unmanned boats for interception operations, and mine hunting operations, already today involving a combination of autonomous and remotely controlled (sub-)surface vehicles. In the future, more launch and recovery movements are likely to be needed in less time and with greater required availability.The most important challenge to be faced is the modularity needed on the mother platform. A wide variety of craft shapes, sizes and weights exist, and naval vessels are expected to outlast several generations of craft.
