Collins Midlife Upgrade/Extension - Companies, Tomahawks and Possible Timings

The most comprehensive, up-to-date Asia-Pacific sub numbers-types map I've seen - at March 3, 2016. Australia's six Collins subs may need to be upgraded with Tomahawk cruise missiles to keep pace with Klubs fitted to Kilo subs of India, Vietnam, China, Russia and perhaps two future Indonesian Kilos.

The leaking of Top Secret Cabinet documents on Future Submarine project timings has prompted Submarine Matters to draw together many details on the Collins "life extension" (or "midlife upgrade"). The midlife upgrade may result in much work for Lockheed Martin in cooperation with Saab and Thales.

The Australian Defence Department apparently has been advising for years that the future subs would not be delivered until the early 2030s. 

Defence sources said the handover of a future submarine by 2026 was always more of a political aspiration (of former Prime Minister Abbott) rather than a sensible shipbuilding schedule.

Australia’s six Collins subs were launched between 1993 and 2001 which, after the standard 30 years of operation, would usually lead to decommissioning between 2023 and 2031. A submarine midlife upgrade would aim to keep them operating until the mid-2030s.

In the meantime a midlife upgrade of the Collins might include more modern sonar, the latest software and hardware for its AN/BYG-1 combat system, derusting, new batteries, overhaul of the diesel engines and maybe introducing Tomahawks. The upgrade would cost much more than A$2 Billion total.

TOMAHAWK CRUISE MISSILES

An additional item which Australia might include in the Collins is Tomahawk (land attack and long range anti-ship) cruise missiles (compatible with the combat system) which would be launched through the torpedo tubes. Wikipedia records: "During the [Collins] construction phase, consideration was given to acquiring submarine-launchable Tomahawk cruise missiles; giving the [Collins submarines] the capability to attack land targets after minor modifications.^[44] Plans to acquire Tomahawk or similar land-attack missiles remained under consideration until 2009, when the Defending Australia in the Asia Pacific Century: Force 2030 white paper was released; stating that land-attack missiles will instead be incorporated into the armament of the Collins-class replacement."

With the future submarine delay a decision not to include Tomahawks could mean Australia falling behind in a region with increasing numbers of submarine fired Klub land attack cruise missiles. This is noting that Kilo diesel electric submarines belonging to Russia, India, China, and Vietnam are being fitted with land attack Klubs missiles (with ranges varying from 300km to 2,500km (depending on user modifications)). Indonesia may also buy two Kilo submarines fitted with Klubs.

UPGRADE WORK FOR LOCKHEED MARTIN, SAAB AND THALES

The life extension may result in much work for Lockheed Martin in cooperation with Saab and Thales. This is noting that the AN/BYG-1 combat system to be upgraded in the Collins is intertwined with the broader sensor, communications and weapon systems of the Collins. Lockheed Martin, Saab and Thales are already working together on submarines solutions. This may allow them to provide an integration solution for most of the upgrades required by the Collins. See Lockheed Martin on Tomahawks for US and UK submarines.

Saab (as early as October 2015) publically anticipated the likely timeline of the Future Submarines and need for a midlife upgrade of the Collins. Nigel Pittaway in DefenseNews, October 10, 2015 reported:

“Saab Pitches Collins Submarine Upgrade

…Speaking at the Pacific 2015 Maritime Exhibition in Sydney last week, a Saab senior executive said …a Collins midlife upgrade [will be] a cost-effective measure to maintain capability…“In Australia, you have decided on a new submarine program, which is fantastic, but it’s not going to be here for a number of years…”

…Australia is looking to acquire up to 12 new conventional submarines under Project Sea 1000, but has a tight timeline if it wishes to avoid further full cycle docking overhauls, which will need to be performed on at least two submarines if the Collins needs extending beyond 2030.

…However, the slow progress of the program is causing concern that the submarines cannot be designed, selected and built in time to avoid a Collins life extension.

…[Gunilla Fransson, Saab’s senior vice president, Security & Defence Solutions] said that if Saab’s proposal for a Collins midlife upgrade is accepted, the work would be undertaken in Australia. “You sustain the Collins boats here in Australia and I don’t see any reason why you could not upgrade them here,” she said.

“Saab would certainly like to position ourselves to support Australia in an extended Collins life of type. You have a very capable local submarine company in ASC, which certainly has the capability to perform the work, together with Saab Kockums and other local Australian companies.”” [WHOLE DEFENSENEWS ARTICLE]
