Malgre resanblans nan fèmen nan aparans nan Tu-144 nan avyon an Anglo-franse supèrsonik, te gen diferans enpòtan nan kontwòl, navigasyon ak motè sistèm yo. Nan zòn tankou ranje, aerodynamic bagay konplike, frenaj ak kontwòl motè, Tu-144 nan dekalaj dèyè Concorde la. Pandan ke Concorde nan itilize yon pake elektwonik kontwòl motè soti nan Lucas, Tupolev pa te pèmèt yo achte li pou Tu-144 a kòm li te kapab tou gen pou itilize nan avyon militè yo. konsèpteur Concorde la itilize gaz la nan avyon sa a kòm awozaj la pou èkondisyone kabin an ak sistèm nan idwolik (gade Concorde pwoblèm # Chauffage pou plis detay). Tupolev enstale plis ekipman sou Tu-144 nan fè sa, ogmante pwa a nan avyon an.

Despite the close similarity in appearance of the Tu-144 to the Anglo-French supersonic aircraft, there were significant differences in the control, navigation and engine systems. In areas such as range, aerodynamic sophistication, braking and engine control, the Tu-144 lagged behind the Concorde. While the Concorde utilized an electronic engine control package from Lucas, Tupolev was not permitted to purchase it for the Tu-144 as it could also be used on military aircraft. The Concorde's designers used the fuel of this airliner as the coolant for air conditioning the cabin and the hydraulic system (see Concorde#Heating issues for details). Tupolev installed additional equipment on the Tu-144 to accomplish this, increasing the weight of the airliner.
