thats enough really
think of its mission. hint is in the name
such mission is limited to COIN. not an all out war against columns of hostile armor. it wont survive long.
in counter insurgency if there is a sighting / tip off a high value target riding in a vehicle or a terror camp .. then this plane can fly over there without much noise disregarding the terrain issues
for more than 2 targets at a time
you call in a purpose built fighting plane
so sir
an armored div (or column) will come in with its own air defense protection and other jets it wont survive a regular military foe
these hybrids are only meant against small entities like smugglers and terror groups.
even much acclaimed A-10 has never flown against Iraq once complete air superiority was achieved and all worthy Iraqi air defense systems were decimated
A-10 is a purpose built jet with much carry weight and power plant for that purpose.
if you upgrade a Mashak to match what A-10 or say Russian Frogger carries then it wont be a Mashak
it will be something else
other American companies proposals
best thing in such situation is go for a clean sheet concept.
like I shared above with that black n white picture
