The Army wants a company to build and deliver MDAC prototypes using existing fielded and mature technologies. MDAC will be air-, rail-, and sea-transportable per MIL-STD-1366; will be able to move rapidly for survivability; have automated high rates of fire with HVP; and have emote weapon firing; have deep magazine capacity, rapid ammunition resupply, and high operational availability. Companies interested also will demonstrate supportability, safety, and cyber security.

Officials of the Army Rapid Capabilities and Critical Technologies Office (RCCTO) at Fort Belvoir, Va., issued a request for information on Monday for the Hypervelocity Projectile (HVP) project.

Army officials want a company able to deliver HVP prototypes no later than fall 2027 for operational demonstrations in 2028, and later for possible deployment. Hypervelocity projectiles fly through the air at speeds of 8 or 9 times the speed of sound.

“Bridge recombination can universally modify genetic material through sequence-specific insertion, excision, inversion, and more, enabling a word processor for the living genome beyond CRISPR,” said Berkeley’s Patrick Hsu, a senior author of one of the studies and Arc Institute core investigator, in a press release.

CRISPR Coup

Scientists first discovered CRISPR in bacteria defending themselves against viruses. In nature, a Cas9 protein pairs with an RNA guide molecule to seek out viral DNA and, when located, chop it up. Researchers learned to reengineer this system to seek out any DNA sequence, including sequences found in human genomes, and break the DNA strands at those locations. The natural machinery of the cell then repairs these breaks, sometimes using a provided strand of DNA.
