Within the early hours of February 11 it was introduced that the Indonesian Defence Ministry had signed a $13.9 billion contract for the acquisition of 36 Boeing F-15 Eagle heavyweight fighter jets from the USA. This made Indonesia the seventh shopper for the fighter after Israel, Japan, Saudi Arabia, South Korea, Singapore and Qatar, with the heavyweight fighters having seen comparatively few exports primarily resulting from their excessive operational prices and upkeep necessities. Indonesia has for the reason that Nineties operated heavyweight and light-weight fighters in parallel, and at the moment deploys a fleet of heavy Russian Su-27 and Su-30 jets complemented by lighter American F-16s. Whereas Russian fighters had been initially anticipated to get replaced by extra trendy Su-35S ‘4++ technology’ fighters, American threats to impose financial sanctions on the Southeast Asian nation ought to purchase high-performance Russian weaponry led Jakarta to change its plans and buy F-15s of their place. 

Though the designation of Indonesia’s F-15s stays unsure, they’re anticipated to be carefully primarily based on the F-15EX at the moment on order for the U.S. Air Power. The Su-35 and F-15EX are each primarily based on rival Chilly Conflict period designs, the previous the Su-27 Flanker and the latter the F-15C Eagle, which had been the prime fighters of the Soviet and U.S. fleets in the course of the interval. Though the Flanker was thought of the extra succesful fighter in the course of the Chilly Conflict, as demonstrated in a number of workouts and simulations and attested to by a number of American navy officers reminiscent of Air Power Chief of Workers Michael Ryan, the collapse of the Soviet Union and sharp contraction of the Russian tech sector allowed the U.S. navy aviation trade to largely bridge the hole. The F-15EX is thus thought of to face a greater likelihood towards the Su-35 than F-15s from the Eighties did towards the Su-27. The newest F-15 variants profit from avionics, information hyperlinks and sensors that are thought of at the least on par with if no more succesful than these of the Su-35. The Russian fighter in contrast has considerably extra highly effective engines, three dimensional thrust vectoring capabilities for improved manoeuvrability, and an prolonged 400km air to air engagement vary utilizing R-37M missiles the place F-15s can solely fireplace an estimated 160-180km utilizing the AIM-120D. The Su-35 additionally advantages from use of triple radars, with two L-band AESA radars embedded in its wings, the place the F-15 makes use of solely a single AESA radar in its nostril. This offers the Russian fighter with distinctive digital warfare capabilities and sure a superior efficiency towards stealth targets.

An vital benefit of the Su-35 program is that the Flanker household of plane to which it belongs has been on the core of Russian tactical fight aviation for the reason that Soviet collapse, with the massive majority of latest fighters acquired for the reason that Soviet collapse being derivatives of the Su-27, the place the U.S. in contrast ceased F-15 acquisitions for nearly 20 years from 2001 producing them just for export. Extra significance has thus been connected to bringing the Su-35 as much as a efficiency customary the place it could possibly take care of the most recent fifth technology fighters, partially resulting from Russia’s lack of its personal fifth technology plane, the place the U.S.’ fifth technology packages have made F-15 modernisation much less of a precedence. Whereas the most recent F-15 variants are effectively matched towards the Su-35, the Russian fighter is predicted to have an edge with benefits in additional key areas of efficiency notably for air to air and anti delivery missions.  

For the Indonesian Air Power the selection between the Su-35 and F-15 can be a detailed one in the event that they had been provided below comparable phrases, with the American Eagle probably advantaged by its larger interoperability with different Western fighters reminiscent of F-16s whereas the Su-35 will be capable to use a lot of the upkeep infrastructure and armaments from the Su-27 and Su-30 and would require considerably much less conversion coaching. The worth distinction between the 2 fighters has been great, nonetheless, with the F-15 provided for $386 million every whereas the Su-35, if acquired in comparable numbers, can be anticipated to price round $78 million relying on the choices added. This locations the F-15’s price at 495 % that of the Su-35, or virtually 5 occasions the value. Rather than 36 F-15s, due to this fact, Indonesia might have bought by far the biggest Su-35 fleet on this planet at 180 airframes – greater than all Su-35s ever produced.

This comparability reductions operational prices, nonetheless, as each plane price comparable quantities to function which means sustaining such a big fleet of both fighter can be unsustainable. Neverthless, a comparability of the 2 fighters’ acquisition prices offers an vital instance of how far more affordably Russia has been in a position to provide heavyweight fighters for export, in addition to the ability the USA wields with threats of financial sanctions to successfully press Indonesia to desert Su-35s in favour of a largely equal fighter for 5 occasions the value. That is regardless of the U.S. additionally putting strict restrictions on how its fighters can be utilized, together with which bases can host them, the place Russia has allowed its fighters for use with virtually no restrictions.
