This summer, June 28, Boeing and Nammo have jointly test-fired a 155mm Ramjet round.
The test at the Andøya Test Center in Norway, the Ramjet 155 was fired from an L39 cannon and its engine successfully ignited, according to a statement from Boeing. 2/
The launch followed years of research, development, and +450 stat & short-range tests.
Boeing and Nammo were awarded a contract in 2019 under the Army’s XM1155 program, an effort to further develop ERCA munition.

“The test — with all aspects from cannon firing, to the projectile body, fins, and trajectory all functioning perfectly — represents a real technological breakthrough in artillery.”
Nammo CEO Morten Brandtzæg said. 4/
XM1155 (AKA THOR-ER - Tactical High-speed Offensive Ramjet for Extended Range) use the solid fuel ramjet (SFRJ) and is an innovative 155mm projectile being developed to meet the requirements of the US Army to hit targets at a range more than 100km. 5/
The revolutionary XM1155 projectile design includes tail rocket motors and large control surfaces to achieve very high altitudes gliding back to Earth and thus the outstanding range >100km. 6/
USArmy in FY23 is funds the program of ERAP 155mm artillery with range out to 150km. Also in FY23 budget, US Army has funded work for a seeker for XM1155 to prosecute moving/relocatable targets. 7/

The russian Army radio communication issue.
russian Army in AFVs uses three basic types of the radios:
- R-123 (Frequency range 27 - 51 MHz)
- R-173 (Frequency range 30 - 75,999 MHz)
- R-168 (Frequency range 30 - 107,975 MHz)
The first two can connected with the R-124 or R-174 tank internal phone. The third one is uses the R-184 AVSK (Аппаратура внутренней связи и коммутации - АВСК)
All these radios can't provide the good communication, first two are very old. The third one is the newest what the russian army has. It is digital and also has Frequency Hopping (FH) and this is the biggest problem of this radio - he can't use the FH to connected with the other old types of the russian army radios, for them it using open frequency, so it's the same shit with the old ones. In case the using the FH, it's also shit - is able to jump frequencies up to 100 hops per second. It's easily intercepted and jammed.
1/
For the last two years, the Russian army and volunteers have been trying to solve the problem with radio communications.
The army chose the R-187 Azart-BV radio (Frequency range 27 - 220 MHz; 220 - 520 MHz). As you can see on the image they trying to adapt these radio to the tank via these metallic construction and connection adapters for the headphones and antenna, but it's quite ineffective and army didn't get any result yet (radios aren't in service, or they are in very small numbers).
2/
The volunteers have choose the Chinese way. They have created the "Sotnik" and "Poltinnik" radios.
Actually these radios are the civilian Lira DM-1000, that is installed inside the metallic boxes and equipped with the adapters for the headphones and antennas and the tank power system.
P. S. the Lira DM-1000 is the Chinese Belfone BF-TM8500 (Frequency range 136-174 MHz; 350-390/400-480/450-520 MHz)

#USArmy YPG tests cutting edge parachute system
The Rapid Rigging De-Rigging Airdrop System (RRDAS), which promises to get Soldiers out of a drop zone and into the fight with the equipment they need faster than ever. 1/
Conventional cargo payloads are typically cushioned with a honeycomb-like cardboard material between the vehicle or other heavy item and the steel palette that carries it from an aircraft to the ground. Even with good cargo parachutes and a perfect landing... 2/
...multiple layers of the honeycomb will collapse upon impact with the ground. RRDAS, however, dramatically reduces the amount of honeycomb necessary to dissipate the force of impact with 10 reusable airbag modules. 3/
It's not even very rare vehicle, it's the 🇷🇺 experimental Light Tactical Vehicle Scorpion LShA, that spotted in the 🇺🇦
The vehicle is manufactured by ZASHITA company and for the 1st time it's presented in 2012. Vehicle was equipped with Polish made diesel Andoria 0501 ADCR. 1/
A small treat about war logistics:
Because all comparing the war in Ukraine with WWI, I decided to provide a small data about the "Resources crisis" of the Entente. 1/
I just share the information from the great book "The Intimate Papers of Colonel House Volumes" by Seymour Charles.
Sadly I have only 3rd volume, in Russian, published in 1939 in USSR. 2/
Some small piece of what 🇫🇷 asked from the US.
André Tardieu, the French politician, served as Commissioner for 🇫🇷🇺🇸 War Cooperation in USA.
(arrived in Washington in 17.05.1917)
According to him, in addition to the planned one, he received additional other demands from France 3/
