In the longer term, Harpoon will need a replacement, and the Type 26 frigate will of course need a weapon system other than the CAMM missile for point air defence. The same article on "Rivista Italiana Difesa" drops in a couple of hints about this as well, and confirms the analysis done on this blog on the latest imagery of the Type 26 concept released by BAE in a January 2012 video: the Type 26 main armament will be carried in a silo counting 24 cells. It is not specified which VLS system will be fitted, but it'll possibly be the Sylver A70. The 24 cells are reportedly going to be used for a modular missile or a family of as common and closely related as possible missiles acting as Harpoon replacement, which is, according to the italian magazine's sources, required to cover three roles:
- Anti Ship
- Land Attack
- Anti submarine
The requirement is still very much flexible and without a well defined shape. Currently, Vertical launch anti-ship missiles aren't exactly around to start with: a VLS Harpoon has been on the cards for years, but never progressed. In addition, there is not an existing missile on the market which is
capable of covering all three roles.

With the first Type 26 expected in service by 2021, it is time to start some serious activity, as only a new design can met all three roles and meet the VL requirement. Little is known of the performances desired from the missile, but a minimum effective range of 200 km has been indicated. The UK and France have begun funding studies by missile maker MBDA for a future cruise missile, potentially for employment from ships and airplanes alike (the latter as a possible longer-term Storm Shadow replacement).
The first results of the studies are visible in the concept "Perseus" that MBDA first showed last year. This missile is roughly 5 meters long (more or less like Storm Shadow) and is said to weight 800 kg (down from 1300 of Storm Shadow) with a range of 300 km or more, the ability to strike ship and land targets with different attack profiles, high speed (more than Mach 3 in certain profiles) and modular space for different warheads to increase mission flexibility. Some 200 kg would be available for the warhead according to MBDA, and they have shown a notional "triple" warhead which features 100 kg of explosive in the missile, along with 2x 50 kg "effectors" that are dropped by the missile in the last stretch of the attack course, to hit either multiple targets in the same area, or to strike a single large target (like a major warship) in several different areas at once for maximum lethality.
Other warhead options would include bunker-buster payloads and others, and if it was possible to use elements of the booster for firing a StingRay torpedo, a Perseus-derived family of missiles could be the answer for SSGW. Importantly, the Perseus is shown by MBDA being launched by VLS cells (as well as from a submarine's torpedo tubes), almost certainly Sylver A70 (the shorter A50 cell, used for example on Type 45, is five meters deep, and Perseus is unlikely to fit in with the vertical launch booster).
