Heavy bombers as in the B-52s ?
They're interceptor/SAM fodder
They only work when you are flying over uncontested airspace which is hard to come by these days.
Maybe Stealth Bombers but no one is selling those and ours isn't ready yet
I have to agree that for a developing country like India heavy bombers would be a burden right now rather than an asset.
Before acquiring any new weapons system the first question that should be asked is that if we need it at all in the very first place; and if we do need it then do we have the budget and third are there cheaper alternatives? Just because China has them doesn't mean that we should go for it too regardless of whether we can afford them or not.
China has bigger problems than India. She's facing off against the world's only superpower USA which is aligned with Japan, South Korea, Taiwan, Australia and a 1/2 dozen other countries in it's vicinity. China's bombers armed with Anti-Ship Cruise missiles are primarily meant as long range platforms for launching area-denial/ anti-access weapons against American carrier battle groups. As far as I can see India has got no such requirement till date.
In India's case where we face two formidable enemies on both fronts any future war would feature heavily contested airspace densely packed with SAM and electronic warfare networks. In such a scenario heavy bombers like the Tu-160 or Tu-22M or Tu-95 Bear would just be restricted to launching long range cruise missiles/ Air-to-Surface missiles from afar for which there are much cheaper alternatives such as road/rail mobile missile launchers which are dirt cheap, can be easily camouflaged and are much harder to detect or heavy fighters such as the Su-30MKI. Although the Su-30MKI's payload is nowhere near these bombers a swarm of fighters could do much more damage than a handful of bombers.
The original mission of heavy bombers is
strategic bombing. However much of that role has been taken over by aircrafts such as the Su-30MKI and SEPECAT Jaguar in the IAF. Today if these bombers were asked to undertake this role they would be huge lumbering SAM/AAM magnets.
Not to mention the additional fighters that would have to be assigned to them as bomber escorts. And what a waste of limited resources would that be! That too in an air force which has been engaged in an eternal struggle since the last two decades to maintain a barely sufficient combat squadron strength.
The biggest concern of all would be the
cost. In today's price a single B-1B bomber would have a minimum flyaway unit cost of 3/4th of a billion dollars (inflation adjusted for 1998 figures). Let that sink in-
US$ 750 million for a single bomber. If you take into account the total lifecycle costs and the fact that defense projects rarely remain within budget such as the USAF F-35 program or the IAF MRCA Rafale deal then it would easily cross $1 billion per bomber. Comparable Russian systems such as Tu-22M and Tu-160 are expected to be marginally cheaper only by a few million dollars.
So my dear sir when you consider the fact that we have struggled to replace the MiG-21 since the 90s and that the not too recent IAF MRCA contract was canceled just because the price of all the contesting fighters doubled in a short span of 5 years, what makes you think that we can afford a bomber in the very first place?
The recently tested Agni-V ICBM carries a price tag of US$ 7 million per unit while the Brahmos cruise missile costs US$ 2.5 million apiece.
That means for a single heavy bomber I could buy ~ 150 Agni-V ICBMs or 400 Brahmos cruise missiles. And I'm pretty darn sure that 400 Brahmos missiles is a better bet than a single Tu-160 any given day.
Future battlefields would involve saturating the airspace with a massive barrage of cruise missiles and UAVs while simultaneously launching fighters to overwhelm and confuse enemy defenses. In order to achieve this we need affordable weapons that can be mass produced not some Cold-War era elephant which can barely defend itself let alone the thought of defending India's territory.
Come to think of it when India's home-grown Arihant class ballistic missile submarines do enter series production then it is estimated to cost US$ 2 billion only. Considering that nuclear ballistic missile subs are the most important component of the nuclear triad where would you rather spend that money?
