An upcoming Russian IRBM missile test on April 20-29

Two Navigational Warnings (HYDROARC 50/23 and HYDROARC 51/23) have appeared that suggest an upcoming Russian missile test of some sort in the Russian Arctic between April 20 and 29, 2023

The initial window is for 20 April, 11:00 to 15:00 UTC. Secondary windows are for 21 and 22 April 05:00 to 09:00 UTC, and 25 to 29 April 05:00 to 15:00 UTC.

The map above shows the locations of the two hazard zones. Launch is from the Barentsz Sea north of Murmansk: the target area appears to be in the East Siberian Sea near the De Long Islands, northeast of Novaya Sibir. The indicated range is about 3500 km, the orientation of the two hazard areas speaks against a lofted trajectory but rather fits a ~500 km apogee.

Initially I considered an SLBM launch, but the indicated range seems a bit short for that - I would expect an SLBM test launch to target the Kura test range in Kamchatka instead. So for now, let's keep it on an IRBM (Intermediate Range Ballistic Missile) of yet-unidentified type.

The ~3500 km range seems a bit too large for either the Zirkon hypersonic missile or Kalibr cruise missiles. So perhaps, this is something new.
