This type of asset would not be used unless for a specific event - battle, confrontation, - a war time scenario. This type of asset his the highest value when it is an unknown that is a factor in a severe loss - not the main reason for failure.
Someone or some group is prematurely detonating, triggering, and controlling the trojan electronics to alert us that they exist, are functional, can be controlled and are deadly.
Wasn't it in the news a few years back that the Pentagon decided not to use Chinese chips and electronic devices for security concerns? Chinese electronics have back door trojans and every ship and aircraft is compromised. The left will dance on our and their own graves in jubilation if our military ends up like the keystone cops on parade.
Back door trojans are also in the average home residential security dvr system as reported last year. This is a known thing and Israel or the Russians - whomever had the ability to trigger the devices - is leaking the open secret that our military is compromised by bad electronics. All thanks to the Obama epoch of self destruction.
