Currently, the Me 163 B-0 has the same basic weight and complete weight as the Me 163 B with the data specified in the game and thunder wiki, except for the gun pod,
but for unknown reasons, it has weakened very slightly to -1m and +1m/sec compared to the Me 163 B-0 in the upward and turning speeds.
However, the Me 163 B-0 is lighter than the B, so there is no clear reason to degrade performance.
Both Me 163 B-0 and B based on the weight of the Me 163 B with non armed pure plane, the MG151/20 2pcs = 84 kg and the MK108 2pcs = 116 kg, This means that the Me 163 B-0 is at least 32 kg lighter than the B version.
and there is also no reason to be heavy due to the quantity of shells.
The MG151/20 including the belt link weighs 200-222g per ammo, the MK108 weighs 480-595g per ammo, the MG151/20 240 rounds weigh approximately 52.8kg - 53.28kg, and the MK108 120 rounds weigh approximately 57.6kg-71.4kg
Assuming that there is no additional device for MK108 recoil control in the B version, And based on the B-0 version without the gun pod installed
Me 163 B-0 MG151/20 : 82kg+52.8/53.28 kg = 134.8 - 135.29kg
Me 163 B MK108 : 116 kg + 57.6 - 71.4 kg = 173.6 - 187.4 kg
The Me 163 B-0 should be about 38.8-52.11kg lighter than the B, and there should be benefits in the speed of increase and turn, but the performance is subtly poor for unknown reasons
Based on the simple calculations above, the Me 163 B-0 is expected to weigh at least 38.8 to 52.11 kg less than the Me 163 B version. This simply assumes that the B version’s MK108 machine gun is removed and replaced with an MG151/20 machine gun.
In the interesting data I found, there is information that the Me 163 B-0 with the pilot and shell removed weighs 1,777kg, so I further specify.
Based on the above data, when adding 1,777kg of empty weight of Me 163 B-0 to 2,173kg of total weight specified in the above data, it should be 3,950kg, which is about 140kg lighter than Me 163 B which is between 2,016 and 2,026kg (to be exact) = 4,090kg
This is the pdf document from which the source was obtained.
And I also found some interesting information that the Me 163 B-0 could fit MK108. This is also shown in the PDF data sheet, and currently the Me 163 B-0 and B(-1a) can be distinguished by engine cover design and the presence or absence of landing gear cover
Looking at the actual photo data I attached, it appears that the cannon barrel near the wing root of the plane, which is presumed to be Me 163 B-0, is not exposed outside the wing, so it may have been equipped with MK108.
In the photo of the aircraft, presumed to be the Me 163 B, you can see the exposed barrel of an MG151/20 machine gun near the wing root.
The Me 163 B series can be considered to have been equipped with either the MG151 or MK108 machine gun, regardless of type.
Perhaps, like the He 162, the supply of machine guns was delayed due to the bombing of German factories at the end of World War II, so it may have been equipped with MG151 or MK108 left in storage as a temporary measure.
Thank you for reading this long post.
