Given the achievements of Israel’s Barak-ER, many have debated whether India should boost the range of its Medium-Range Surface-to-Air Missile (MRSAM) by simply attaching a larger booster.
From an engineering perspective, this modification is highly practical. Israel has already proven this approach works, attaching a bigger booster to the Barak-8 interceptor to stretch its strike distance from 70–80 kilometres to a much wider 150 kilometres.
India partnered with Israel Aerospace Industries (IAI) to create the MRSAM and has previously looked into ways to lengthen the weapon's reach.
Yet, instead of creating an "MRSAM-ER" to cover the 150-kilometre zone, the Defence Research and Development Organisation (DRDO) has chosen to pour its efforts and funding into an entirely different initiative: the Project Kusha long-range air defence programme.
While a theoretical extended-range MRSAM and the new Kusha-M1 missile would target threats at a similar distance, their underlying designs and foundational concepts are vastly different.
An upgraded MRSAM would merely be a modified version of the older Barak-8 framework. The core components, including the seeker, guidance technologies, and main interceptor body, would still rely on the original joint Indo-Israeli blueprint, with the new booster serving solely to push the missile further.
In stark contrast, Project Kusha is being built from the ground up as a fully home-grown series of long-range interceptors. This new family of missiles is intended to serve as the ultimate shield for India's upcoming national air defence grid.
A major separating factor is the sheer performance of the weapons. Even though a boosted Barak-8 could travel further, the interceptors in Project Kusha will utilise far more powerful propulsion technologies created specifically for long-distance strikes.
Defence experts note that Kusha’s missiles will boast much faster terminal velocities, making them far better equipped to destroy high-speed dangers like modern cruise missiles and specific types of ballistic weapons.
The structural layout of the entire defence initiative is another key difference.
Project Kusha is structured to be a tiered defence network, featuring a variety of missiles designed to intercept threats at increasing distances.
Currently available data suggests the system will feature three distinct interceptors, referred to as M1, M2, and M3, capable of striking targets at roughly 150 kilometres, 250 kilometres, and an impressive 350 to 400 kilometres.
Building these three missile types on a unified platform brings massive logistical benefits. By sharing the same launch pads, command centres, software networks, and maintenance routines, the military can streamline its operations and significantly cut down on long-term expenses.
If India were to introduce a separate, boosted MRSAM just for the 150-kilometre layer, it would force the armed forces to manage a completely parallel supply and maintenance chain, hindering the goal of a single, cohesive air defence environment.
Above all else, the drive for total strategic independence is the most crucial factor behind this decision.
The current land-based MRSAM stands as one of India's proudest joint ventures, greatly boosting the protective power of both the Indian Army and the Air Force.
However, because it is a shared Indo-Israeli creation, the foundational technology and intellectual property are split between the two nations.
On the other hand, Project Kusha is a 100% domestic endeavour, designed and produced entirely by Indian entities like DRDO, Bharat Electronics (BEL), and Bharat Dynamics Limited (BDL).
This approach gives the nation absolute authority over software updates, manufacturing speed, future exports, and how the system merges with other Indian communication networks.
This level of independence is vital as Project Kusha is slated to become a core foundation of India's growing integrated air defence grid.
It will operate side-by-side with the formidable Russian S-400, homegrown Ballistic Missile Defence (BMD) networks, and the overarching Integrated Air Command and Control System (IACCS).
Despite this shift in focus, a modified, longer-reaching Barak missile is not completely out of the picture.
The Indian Navy might still find an extended-range Barak highly appealing. Warships have very tight space constraints in their vertical launch tubes, meaning a compact missile that can travel far is incredibly useful.
Therefore, a Barak-ER equivalent could still serve a critical role in protecting the fleet at sea, acting as a supplement to Project Kusha rather than a replacement.
For the land and air branches of the military, however, the path forward is firmly set.
Instead of pouring money into two different missile systems that do the same job, India is cementing Project Kusha as the bedrock of its long-range sky defence.
By producing a fully domestic, multi-tiered family of interceptors, the DRDO intends to weave a single, impenetrable defensive net.
This unified ecosystem will be tasked with shielding the nation's most critical assets from enemy jets, cruise missiles, drone swarms, and other next-generation airborne dangers.
Project Kusha: Latest Updates and Timelines
To fully grasp the scale of Project Kusha, it helps to look at the latest developments surrounding the ₹21,700 crore project. Often compared to global top-tier defence networks, the system is advancing rapidly toward an expected phased induction between 2028 and 2030.Defence Minister Rajnath Singh recently praised the initiative, referring to it as a "game changer" for India's security landscape during a recent address in Hyderabad.
The successful initial testing of Project Kusha missiles was announced in early 2026, marking a significant milestone in India's journey toward total self-reliance in cutting-edge military technology.
