The "Block III" standard includes multiple "energy saving" features into production models.

The ASM-11 Sirena is an Inyurstan subsonic anti-ship missile. Known for its light weight and large number of versatile variants, the Sirena is one of the most widely produced and exported missiles in the Inyurstan arsenal.
Overview
With a baseline weight of 375kg, and a base length of 3.6m, the ASM-11 can be carried by both helicopters and fixed wing aviation. Later models were adapted to launch from trucks and surface ships.
A wide variety of guidance options are available, though in most cases an active radar guidance is used. During the Lolloh-Ruol Wars, TV-guidance grew in popularity among naval aviation crews for several reasons, including: 1) better discretion against passive decoys and maritime clutter, 2) the ability to manually direct the missile onto a specific section of the ship.
Variants
ASM-11
ASM-11E+ (Block II)
ASM-11E3 Êconoméa Effícianté: Dubbed the "Triple E", the ASM-11E3 is a mass-production and export model. To save costs, multiple commercial-off-the-shelf parts are used, and a more simplistic GPS/TIMU flight computer is used. The active radar warhead only kicks in within terminal range, to save battery life and cost, for homing guidance.
ASM-11M+ (Block III)
The "Block III" standard includes multiple "energy saving" features into production models. Such features include improved glide wings, improved jettison-able rocket booster and delayed-sea skimming modes. By delaying the sea skimming profile, the missile can act as a glide weapon at more medium altitudes and slowly descend towards the surface prior to following a less-efficient sea skimming profile below enemy radar.
ASM-11M: The standard "Block III" model, the ASM-11M uses an active radar homing warhead along with GPS/TIMU for navigation, and then assistance from an IR homing warhead for terminal guidance.
ASM-11M2: Fitted with a multisensor autonomous-targeting seeker, similar to that on the ASM-13 Scylla, the ASM-11M2 is currently the most capable variant of the Sirena family. Able to specifically target a subsection of an individual ship, the seeker can also "avoid" clutter, non-target, and high-emissions "threat" points as it navigates to the target. Because of this warhead type, the ASM-11M2 can function when the "kill chain" has been lost.
