A probe is a device that contains a number of general purpose or mission specific sensors and can be launched from a starship for closer examination of objects in space. There are nine different classes of probes, which vary in sensor types, power, and performance ratings. The spacecraft frame of a probe consists of moulded duranium-tritanium and pressure-bonded lufium boronate, with sensor windows of triple layered transparent aluminum. With a warhead attached, a probe becomes a photon torpedo. The standard equipment of all nine types of probes are instruments to detect and analyze all normal EM and subspace bands, organic and inorganic chemical compounds, atmospheric constituents, and mechanical force properties. All nine types are capable of surviving a powered atmospheric entry, but only three are specially designed for aerial maneuvering and soft landing. These ones can also be used for spatial burying. Many probes can be real-time controlled and piloted from a starship to investigate an environment dangerous hostile or otherwise inaccessible for an away-team.

Computer Systems
Number of computer cores: Two; The primary core one occupies space on decks 7, 8 and 9 far astern. The secondary, emergency core is much smaller than the first and is located adjacent to Environmental Control on Deck 16.
Type: The updated Computer cores found on the Akira class are newer versions of the Galaxy Class Isolinear Processing cores. The system is powered by a smaller, regulated EPS conduit directly from the warp core. Cooling of the isolinear loop is accomplished by a regenerative liquid nitrogen loop, which has been refit to allow a delayed-venting heat storage unit for "Silent Running." For missions, requirements on the computer core rarely exceed 45-50% of total core processing and storage capacity. The rest of the core is utilized for various scientific, tactical, or intelligence gathering missions - or to backup data in the event of a damaged core.
