No way AN225 OEW is 175t.
AN124 OEW is around 175-185t, and AN225 is basically enlarged AN124, 2 more engines, longer airframe, double tail, different wing etc. Although I cannot find any trustworthy reference to AN225 OEW but I estimate it is well well over 200t, and honestly I think it is probably closer to 300ish if I do a reverse engineering (200t payload range translated into flight hours, MTOW less 200t payload, less estimated fuel for quoted range + reserves, etc).
