What is the difference between the Su 27 and the Su 30?

The Su-27 is mainly based on seizing air supremacy, so his maneuverability is better, and the electronic equipment is also mainly used to serve air combat. The role of the Su-30 is the same as that of the US military's F-15E, mainly carrying out ground attacks, and its air combat capability has decreased a lot, and the radar and electronic equipment equipped with it are mainly ground-based. In terms of appearance, the Su-30 is a little taller than the Su-27, and it is obvious that the two aircraft are put together.

The Su-27 is an air superiority fighter, mainly used for homeland air defense operations, and has poor ground strike capabilities. The Su-30 is a combat bomber based on the Su-27, which emphasizes the ground strike capability when taking into account the air combat performance, and the load and range have been increased.

The Su-27 is the first member of the Flanker family developed by Suwutong Hoy Company, and the follow-up models include Su30, Su33, Su34, Su35, and Su37, all of which are upgraded and improved versions of Su27. China currently has both 27 and 30. Both of these fighters are heavy fighters, and the difference is that they are upgraded versions of the 30 to 27.

In fact, the two are the same model. All were developed on the T-10s with a different focus on knowledge development.

The Su-27 is an air superiority model. And the Su-30 is a multi-purpose model.

This is similar to the old American F-15, such as the F-15C is an air superiority type. The F-15E is a multi-purpose ground attack version).

Of course, because of the difference in combat missions, there are differences between the two in some equipment.

Let's look at the N27E type equipped with the Su-27SK in terms of airborne radar. Empty mode only. The detection range is 80-100km

This is also the reason why there is almost no guidance ** in the ground attack ** of the Su-27)).

And the N30VE type that the Su-001MKK is equipped with. In addition to retaining its powerful air combat capabilities. Added open space mode.

In air-to-air mode, the detection range is 90-110kmThe detection of ground targets in air-to-ground mode is 70-80km, and for large ships at sea.

200-250km.

It is precisely because of this that the Su-30 has a strong ground attack capability.

In other ways. For example, the Su-30 is equipped with an AL-31F turbofan engine with greater thrust than the Su-27 equipped with AL-31F2. to fit.

Large amount of ammunition. The need for a large voyage. This is all required for an obvious ground attack.

In fact, the Su-33 shipwreck and the Su-35 multi-role fighter are both modifications of the Su-27. However, the performance has been greatly improved compared to the prototype.
