19FortyFive columnist Harrison Kass noted the high efficiency of the TOS-1A Solntsepek in certain conditions. The Kass article was published on the media website.

According to a retired US Air Force pilot, TOS-1A thermobaric warheads are sometimes referred to as "vacuum bombs". The author noted that weapons are almost 100 percent fuel. Thanks to this feature, Sunshine can deal more damage than warheads of other weapons systems of comparable weight.

Harrison Cass called thermobaric warheads effective when used in buildings, trenches or trenches - in this case, the attack of the "Sunfish" becomes very deadly. The main advantage of warheads is that the blast wave lasts longer than a conventional explosion.

The material also notes the shortcomings of this type of weapons. The weapon is very dependent on oxygen, so under water, at high altitude or in adverse weather conditions, TOS-1A ammunition may be ineffective.
