IMO BETTER WOULD BE IF WE TRY TO BUILD SU 30 WITH COMPOSITS AND ADVANCED ELECTRONICS.
As I had mentioned use of Composites.
Let me list some of the Advantages of Use of
Composites or composite materials as a whole :
Advantages of Composite Materials
1)Design Flexibility – Thermoset Composites give designers nearly unlimited flexibility in designing shapes and forms. They be molded into the most intricate components and can be made a wide range of densities and chemical formulations to have precise performance properties.
2)Low cost per cubic inch – When comparing costs based on volume, thermoset composites have lower material costs than traditional materials such as wood, engineered thermoplastics and metals. In addition, because thermoset composites have a low petroleum-based content, they are not subjected to the price fluctuations experienced in petroleum-based products.
3)Lower material costs – Because thermoset composites can be precisely molded, there is little waste and therefore significantly lower overall material costs than metals products.
4)Improved productivity – Industrial Designers and Engineers are able to reduce assembly costs by combining several previously assembles parts into a single component. Also, inserts can be molded directly into the part during the molding process thereby eliminating the need for a post-process. In addition, composites do not usually require additional machining, thereby reducing work-in-process and time to market.
Other key advantages include:
As molded dimensional accuracy,
Tight tolerance, repeatable moldings
Low-post mold shrinkage
Chemical Resistance
Consolidated Parts and Function
Corrosion Resistance
Design Flexibility
Durable
High Flexural Modulus to Carry Demanding Loads
High Impact Strength
High Performance at Elevated Temperatures
Heat Resistance
Naturally Flame Retardant
Creep Resistance
Mechanical Property Retention
Superior Thermal Stability
Lighter Weight than Metal
Lower Costs vs. Die Cast
Low Petrochemical content
Better cost stability than commodities
Lower Cost per Cubic Inch as compared to Thermoplastics
Molded-in Color
Molded in inserts
Outstanding Electrical Insulation
Arc and Track Resistance
Ability to Quench
And many more!

But there are also some Disadvantages associated with composites. That's all I have to Say. Good day
