The "RQ-180" time-frame (2008) when that program began (refer to a previous post of mine regarding dates). There could have been some NGC FB-23 development work for LRS-B/Theater Strike as well. Sometimes you don't know when demonstrators had been built, it depends on how sensitive the program is, does the platform have an application advantage and as long as you keep them hidden. Kind of like the NGAD demonstrator platform.
