This novel aerial glide bomb, touted by the Russian media as stealthy, was formally unveiled by the state protection enterprise, Rostec. Additional validation got here through quoted statements from a Rostec consultant on Russia’s information company TASS. Rostec has affirmed that each one ministry-designated assessments have been efficiently carried out, establishing the Drel’s capabilities in keeping with their anticipations. 

Nevertheless, precise particulars surrounding using Drel in Ukraine stay strictly categorized, masking the specifics of its operation. Moreover, the timeline and scale of Drel’s mass manufacturing, together with the projected completion of the primary batch, stay undisclosed.

What can we find out about Drel?

Whereas particular particulars stay restricted, conjectures from each Japanese and Western navy consultants abound. 

As per an article in The Nationwide Curiosity [NI], the invention will seemingly be a cluster glider bomb stealth. It’s anticipated to be managed by the GLONASS international navigation satellite tv for pc system, weighing over 500 kilograms with a attain spanning 30 to 50 kilometers. 

The ‘Drel’ unit will seemingly comprise 15 homing warheads, strategically outfitted with each a friend-or-foe detection system and digital countermeasures for superior operation.

A delay

Regardless of plans for serial manufacturing to start in 2021, the rollout of the Drell skilled some hiccups. As reported by BulgarianMilitary.com, manufacturing didn’t go as initially deliberate by the Russian Federation. 

Quick ahead to 2021, when it turned evident that Drell’s manufacturing confronted insurmountable challenges. Underneath the revised blueprint, mid-2022 was set for the completion of all crucial evaluations, inclusive of official state testing. Sadly, this goal was additionally missed. It was not till mid-end 2023 that these assessments had been lastly carried out efficiently.

Discussions across the “Drel+Su-57” emerged for the primary time again in 2018. This was when Alexander Kochkin, the Deputy Normal Director of Tehmash, declared that this next-level fighter would function the bomb service. The Sukhoi Su-57 is ingeniously designed to incorporate each inner and exterior hardpoints, outfitted for carrying various armaments. 

The first spot for the Su-57 to withhold armaments is its inner weapon bays. This aware design performs a important position in sustaining the plane’s stealth traits. Nestled inside the plane’s fuselage, these bays can home a plethora of weapons starting from air-to-air, air-to-surface, and anti-ship missiles, to precision-guided bombs. 

We should not overlook the truth that the Su-57 comes with exterior hardpoints positioned beneath its wings. These come into play when stealth isn’t the necessity of the hour, or when the plane must accommodate further or extra substantial weapons that may’t be fitted within the inner bays. Very similar to the interior bays, these exterior hardpoints are able to holding a related number of weapons, together with bombs.

GLONASS

Whereas particulars in regards to the Drell aerial bomb are considerably sparse, what we do know is that it contains GLONASS expertise for navigation. Created by Russia, GLONASS, or the International Navigation Satellite tv for pc System, presents immediate navigation help for each civil and navy functions. 

This satellite tv for pc system is cleverly positioned in a mid-circular orbit, about 19,100 km [or 11,900 mi] up, with an inclination of 64.8°. With an orbital interval lasting 11 hours and 16 minutes, these satellites full a full cycle, returning to the identical location each eight sidereal days – which is equal to 17 full revolutions. 

A particular high quality of the GLONASS system is its effectiveness in increased latitude areas, each within the northern and southern hemispheres. It stands out because of this, delivering dependable navigation alerts in areas the place conventional GPS programs usually falter. 

The system’s structure—a complete of 24 satellites unfold throughout three totally different orbital planes, every encompassing exactly eight satellites—ensures optimum international protection. Russia will get by with 18 of those satellites offering its protection. For the aim of correct positioning, a receiver needs to be inside the sign vary of not less than 4 satellites.
