In the USA: The risk for the B-52H missile carrier during unsuccessful tests of the AGM-183A ARRW hypersonic missile was not zero

Recently, reports came from the United States about unsuccessful tests of a promising hypersonic air-launched missile AGM-183A ARRW. As already reported by Voennoye Obozreniye, the rocket left the pylon, but almost immediately exploded when its own engine was turned on. Recall that the tests were carried out using the US Air Force B-52H Stratofortress strategic bomber as a carrier.
In a release from the US military, it was reported that the engine of the AGM-183A ARRW rocket was ignited. After that, a commission was formed, which began to study the circumstances of unsuccessful tests of hypersonic weapons American made.
According to the latest data, the commission at the preliminary stage of its work identified problems that are associated with the fuel used. It is stated that at the moment of ignition, excess energy is generated, which leads to the ignition of "a significant volume of rocket fuel." In turn, the implementation of the "withdrawal" of excess energy, by and large, is already meaningless, since volumetric detonation occurs. As a result, the rocket simply explodes.
An important aspect that the American commission draws attention to is that during flight tests "the possibility of hitting the carrier with the tested hypersonic missile was not completely ruled out."
American experts say that, in fact, there was a risk of hitting the carrier aircraft. After all, the detonation of the rocket fuel immediately after the start of its engine operation could pose a threat when taking into account the relatively small distance at which the hypersonic munition was located from the aircraft.
Experts referring to the US Air Force Commission:
At the moment, the parameters of the dynamics of the rocket at the time of its explosion and, most importantly, its distance from the B-52H Stratofortress are being studied. Based on these parameters, a modified concept of new tests will be developed, which, it is reported, should be reduced to "zero risk" for the carrier aircraft.
