According to available information, ballistic missiles and other ground launched systems will be used in 1-2 hours from now, approximately between 1:30-2:30am local time.

Up to 30 missiles (RM-48U, Iskander-M, Oniks-M, & Zircon) could be used in total. The highest threat is to Kyiv City, Kyiv Oblast, Dnipropetrovsk Oblast, Kharkiv Oblast, and Poltava Oblast.

There is also the possibility of up to 10 Kn-23 ballistic missiles being launched from near Liski, Voronezh Oblast, in around this same timeframe.

Currently, approximately 40 Geran-2/4/5 drones are detected in Ukrainian airspace.

Sorry, got the timing wrong on the strategic bombers. The Tu-95MS are expected to take off from Olenya Airbase in around an hour.

Some of the Tu-95MS strategic bombers are already airborne from Olenya Airbase, having taken off a few minutes ago.

They are flying south to their launch lines in western Vologda Oblast, which they will reach in around 1.5 hours. The 5 Tu-160M strategic bombers are expected to reach these same launch lines at around the same time.

From there, it will take a little under 2 hours for the Kh-101 cruise missiles to enter Ukrainian airspace. Up to 70 missiles will be launched in waves towards Ukraine.

At least 6 Tu-95MS are airborne.

Approximate flight routes of the Russian Tu-95MS and Tu-160M strategic bombers airborne right now.

They will reach the launch lines in western Vologda Oblast in around 90 minutes, and launch 50-70 Kh-101 cruise missiles towards Ukraine (Sumy/Kharkiv Oblasts) in several waves.

For the next hour, there is an increased threat of ground-launched missile strikes against Ukraine.

Russia may launch up to 30 Iskander-M and RM-48U modified S-400 ballistic missiles; as well as Zircon hypersonic and Oniks-M supersonic cruise missiles. Up to 10 Kn-23 ballistic missiles could also be launched alongside this.

Additionally, there is a possibility of 8-24 Kalibr cruise missiles being launched from either the Black Sea (Novorossiysk Naval base) or the Caspian Sea (Kaspiysk Naval Base) during this period, although they may be timed to enter Ukrainian airspace alongside the Kh-101 cruise missiles.

7 Tu-95MS strategic bombers are now confirmed to be airborne from Olenya Airbase, alongside the 5 Tu-160Ms from Ukrainka Airbase.

It's likely that the number of Tu-95s airborne is closer to 10, but so far only 7 have been confirmed.

Currently detected in Ukrainian airspace:

~20 Geran-2/Gerbera drones
~10 Geran-4 jet-drones
~4-5 Geran-5 jet-drones
