Boeing's offer to Poland was for “AH-64EV6, with MUM-T [manned-unmanned-teaming] capability," Adam Hodges, Capture Team Lead for Vertical Lift International Sales at Boeing Defense, Space & Security, had told reporters at MSPO,
according to Breaking Defense. However, "the level of interoperability will be detailed on [the] base of government to government talks, and will depend on customer requirements and US Government."
The V6 subvariant of the AH-64E is one of, if not the most modern configurations of the Apache. The U.S. Army is in the process of bringing its AH-64E fleet up to this standard, which includes a raft of improvements and new capabilities, beyond the improved ability to work cooperatively with unmanned aircraft. Compared to earlier AH-64Es, V6 types feature an expanded suite of sensors, as well as communications systems and data-links, which improve their ability to spot and engage targets, especially during over-water operations, as well as detect and avoid threats.
