The Iron Dome missile guidance shall bring the missile to the optimal engagement position. The interceptors missile don’t hit the incoming rockets directly, rather explode very close to them. The detonation is triggered by the interceptor rocket’s proximity fuse.

/1
To be successful, the Iron Dome missile needs to destroy the incoming rocket warhead. Hits in the back-end (rocket motor section), do not affect the outcome of the engagement because the warhead will fall and the explode which can be anywhere along the trajectory.

/2
For the defender, if the calculated impact point is disrupted, it is often presented as a successful intercept, but in reality if the warhead explode anywhere in Gaza or Israel (and cause the casualties) it can't be counted toward the successful interception rate.

/3
Bottom line: every claim about the successful interception percentage rate shall be taken with reserve.

8 May
WWII in Europe officially ended 23:01 on 8 May. The Soviet Union celebrates Victory Day on 9 May, as the end of operations occurred after midnight Moscow time. Nazi Germany was crushed by the Soviet forces who took the largest brunt but the Nazi virus escaped Berlin...

... escaped virus took ratlines, mutated, took different shapes, streams... embedding itself in the politics and political parties, hiding behind the policies, organizations, institutions, banks... it change the uniforms, the languages... popping up from time to time...

/2 ImageImageImageImage
... after some time it reappeared openly... firstly in one small area in the Balkans, then started more on the east... for this virus, there is a vaccine, but the mutated virus took the vaccine "manufacturers" and embedded itself in the governments and treaties...

New 🇺🇦 AD system "Кильчень" (Kilchen) is proposed by design bureau "Южное" (Yuzhnoe). According to Yuzhnoe, the system will have several command posts and some of them will be located in virtual "clouds". The price of the system will be 1/4 or 1/3 of the price of Patriot.

/1
The developer claim that such virtual CP system is almost impossible to destroy with conventional weapons. The typical unit may consist of 4-6 TEL. Each TEL has 4 missiles with a maximum range of 280 km. AD includes 🇺🇦 OEM detection and targeting X, C and S-band radars.

/2
Theoretically, AD system can simultaneously engage 12 targets of which can be 6 ballistic (guiding 4 missiles per target) or up to 16 aerodynamic targets (guiding 2 missiles per target). AD system will use an active millimeter-wave radar homing head.

Seem that the situation is escalating in Donbas on an hourly basis... Intensive artillery on both sides. Russian media reported Kirovsk, Bryanka, and Stahanov. Air activities near Chuguev, Ukr helicopters flying toward Donetsk.
This may be the sign of a wider attack but also can be the counterbattery fire (which is not unusual). Lare calibers are involved, based on the sounds of detonation and explosion flashes.
Besides this, still, there is the hope of de-escalation if common sense prevails.
Looks that in the Donetsk area mostly 120 mm mortars were fired. Easy to fire then change the position fast, then open fire again.

It is well known that the US is the first country to develop stealth technology, but how many people are aware that stealth would be impossible without an "industrial-strength" theory developed by Soviet scientist, Dr. Peter Ufimtsev (Пётр Уфи́мцев) in early 60s.

The “The method of edge waves in the physical theory of diffraction” work was devoted to a physical and mathematical algorithm by which it was possible to calculate the scattering area for an aircraft of any shape.

/2 ImageImageImageImage
Denis Overholzer worked in the office of Lockheed Martin in the early 1970's. He gave translated work directly to the engineering staff. Those, being true experts in their field, penetrated into the work of Ufimtsev and almost immediately understood what was happening.

Russian naval bases are well protected: it appears that 92N6A and 96L6-1 radars are positioned on the high ground above the port.
This base looks like Severomorsk, but can't say for 100%.

One of the positive things that former Yugoslavia have done was a development of the domestic defense industry which among others included artillery, training and combat aircraft, munition and MBTs. Modern MBT was M-84.
The further improvements was designated as M-90 Vihor.

/1 The M-84 is based on the Soviet T-72 but with many modificat
The chassis is similar to M-84/T-72, but is topped with a new chevron-shaped turret with rounded edges. It has a high p/w ratio of 27.27 hp/T; Propulsion is provided by a V46-TK1, a diesel V12 engine with 1200 hp. The main gun is is 125 mm developed from the Soviet 2A46.

/2
The electronics are an improvement over the M-84, with a thermal imaging system, laser rangefinder, and a digital ballistics computer as standard equipment. A hunter-killer capability via the TC's periscope was claimed as well.
