Yeah HD is marketing speak in that context, current DAS is less than 1MP (he might mean that the stitched image is HD, which is true).
Well, this is actually old DAS from NG.
Afaik, not in the production anymore.
New EODAS from RTX has been delivered to Lockheed Martin to be integrated with Lot 15-17.
"The sensors use two key components from across RTX: the strained layer super lattice (SLS) detector material (from commercial foundries) is processed using the same revolutionary manufacturing techniques to develop the GaN semiconductors in Andover, Massachusetts, which power Raytheon radars such as Patriot, SPY-6, and LTAMDS. The EODAS SLS detector material is then integrated into focal plane arrays by engineers at Raytheon Vision Systems in Goleta, California. These advancements, coupled with digital pixel technology and a digital read-out integrated circuit, give pilots a quick, high-definition picture of everything around them, culminating in a more capable missile detection system."

No definite specs yet. (That I know of)
But seems new EODAS from RTX is significantly improved.
