Ukrainian air defence work:

As of the time of writing, it appears that Ukrainian air defence was able to intercept at least 6 Iskander-Ks and 3 Iskander-M/S-400 decoys.

-----------------------

The main targets for this strike was Ukrainian energy infrastructure. The following was targeted:

"Kyiv" 750 kV electrical substation, Kyiv Oblast (50.49441, 29.69235) by ~15 Kh-32s and 2 Zircons.

Prydniprovska Power Plant, Dnipropetrovsk Oblast (48.40533, 35.11202) by 5-15 Iskander-Ms.

"Bar" 330 kV electrical substation, Vinnytsia Oblast (49.08317, 27.74369) by ~9 Kh-101s and ~6 Iskander-Ks.

Trypillya Thermal Power Plant, Kyiv Oblast (50.1339, 30.74764) by ~6 Kh-32s and ~6 Iskander-Ks.

Dneprovsky Plant of Electrical Equipment, Dnipropetrovsk Oblast (48.47739, 34.987767) by 2-8 Iskander-Ms.

"S/S Vynnytska" 330 kV electrical substation, Vinnytsia Oblast (49.1598, 28.49138) by ~9 Kh-101s.

CHP-5 Power & Heat and Power Plant, Kyiv Oblast (50.39403, 30.56928) by ~4 Iskander-Ms.

Kharkiv TEC-5 Combined Heat and Power Plant, Kharkiv Oblast (49.9707, 36.11154) by ~3 Iskander-Ms.

Zmiivska Power Plant, Kharkiv Oblast (49.58579, 36.52436) by ~4 Iskander-Ms.

CHP-4 Combined Heat and Power Plant, Kyiv Oblast (50.44693, 30.64255) by ~2 Iskander-Ms.

Unknown target near Pavlohrad, Dnipropetrovsk Oblast, by ~1 Iskander-M.

Another unknown target near Pavlohrad, Dnipropetrovsk Oblast, by ~1 Iskander-M.

There were 3 of these interceptions, which I have visually confirmed. Unfortunately I cannot post the videos here, for obvious reasons.

"The Schizophrenic Front"

Satellite imagery shows significant damage to the Zmiivska Thermal Power Plant in Kharkiv Oblast, including the 330 kV and 110 kV substations, along with 4 of the generator transformers, as a result of Russia's most recent combined missile attack.

5 craters from Iskander-M ballistic missiles are visible, which is 1 more impact than what I previously reported.

Notably, the TPP has halted all power generation.

Satellite imagery shows that the "Vinnytsya" 750 kV electrical substation was targeted in Russia's most recent combined missile attack on Ukraine.

2 craters from Kh-101/Iskander-K cruise missiles are visible at the substation, while a third crater is seen in the neighbouring field ~390 metres away due to one of the missiles missing its target.

Satellite imagery shows new damage to the CHP-5 Combined Heat and Power Plant in Kyiv, after it was hit by 4 Russian Iskander-M ballistic missiles in the most recent combined missile attack on Ukraine.

A large burn mark is visible, and it has entered an emergency shutdown mode.

Satellite imagery shows new damage to the CHP-4 Combined Heat and Power Plant in Kyiv, after it was hit by 2 Iskander-M ballistic missiles

Both craters are visible in the red circle. The other craters in the imagery are from previous strikes.

As a result of the strikes, CHP-4 has entered an emergency shutdown mode.

Satellite imagery shows new damage to the "Kyiv" 750 kV electrical substation after it was targeted by numerous Russian Kh-22/32 cruise missiles and Zircon hypersonic cruise missiles.

Notably, a number of craters and burn marks are visible outside the substation, indicating that some of the less accurate Kh-22 missiles were used alongside Kh-32s.

Damage is also seen to the substation itself in at least three locations due to missile impacts.

High threat of Iskander-M launches from Taganrog, Rostov Oblast.

Tu-22m3 strategic bomber over the Black Sea.

Unidentified missiles near Kushuhum, Zaporizhzhia Oblast, and Khotin, Sumy Oblast.

Explosions in Zaporizhzhia. Either Kh-22/32 or MLRS.

The missile near Sumy disappeared, probably MLRS

The missile near Zaporizhzhia was also MLRS, which targeted something south of the city.

The Tu-22m3 appears to just be carrying out a patrol in the eastern Black Sea, alongside a Su-57.

Tomorrow there is expected to be an exchange of POWs between Ukraine and Russia, with each returning 157 people to the other.

4 Tu-22m3 strategic bombers are airborne from Olenya Airbase, Murmansk Oblast, flying towards their launch lines near Unecha, Bryansk Oblast.

They will land at Dyagilevo Airbase, Ryazan Oblast, to be equipped with Kh-22/32 cruise missiles.

HIMARS launches from Kharkiv Oblast to Belgorod

S-300/400 launches from Belgorod City

Only one HIMARS was used, and was shot down near the international border by S-400.

Multiple Ukrainian Su-24s from Myrhorod Airbase, Poltava Oblast, are also airborne over Kharkiv Oblast.
