Meet Nomad. It lives in a tube and could be a very interesting
The Naval Research Laboratory has been testing a light rotary drone called the Nomad from USS Coronado (LCS-4). The cool thing about it is that it is CO2 launched from a tube, and they can carry (and operate) multiple Nomads at once.
According to NRL:
The Nomad is a highly affordable expendable design, allowing for execution of its mission without concerns for returning to the ship. This new upgrade retains the original affordable expendable design, but now has a recovery feature that allows operators to retrieve and reuse the Nomad vehicles multiple times in support of development, testing, training, and potentially future operational missions.
A kinda interesting concept, especially if you allow the tech to grow to where a single LCS could serve as a “drone carrier” flying dozens or even possibly hundreds of small tube-launched Nomads or weaponized successors operating in swarms. Now that actually sounds like a useful littoral combat ship.
