MELBOURNE: The sinking of the 40-year-old Indonesian submarine and the lack of Indonesian Navy personnel on board in waters north of Bali final week have brought on reverberations in Indonesia because it grapples with the devastating loss.
Among the questions requested within the wake of the incident is the viability of continuous to function ageing defence platforms – and extra broadly, how the recurrence of such a tragedy might be prevented when the nation had just lately commissioned three extra submarines over the previous 5 years.
More voices are pushing for a sister submarine KRI Cakra to decommissioned, or at the very least grounded till its seaworthiness is verified.
This is regardless of analysts rightly declaring that Indonesia, with its huge land space, territorial waters and airspace, wants a certain mass of defence platforms but has to strike a stability because of a restricted price range.

INDONESIA’S OLD PLATFORMS
Analysts have additionally identified it makes little fiscal sense for armed forces to withdraw billion-dollar gear earlier than their full service life has been reached except there are compelling causes for doing so.
Investigations into the causes of the submarine sinking might shed extra mild, however for now, no new purpose has surfaced. And so the Indonesian navy will proceed working older, even second-hand platforms to make sure the archipelagic nation has ample belongings to make sure its defence.
These embrace a fleet of former East German naval vessels procured and refurbished within the Nineteen Nineties, British-built Hawk trainers and lightweight assault jets already in service for over three many years.
The Indonesian navy additionally operates the Lockheed-Martin C-130 Hercules transport plane, a few of that are over 60 years outdated.
It has additionally lately acquired former US Air Force F-16 fighter jets upgraded to newer requirements, and checked out used Eurofighter Typhoon fighters withdrawn from use by Austria, as Indonesia seeks to modernise its air drive and broaden its potential to defend it huge airspace.
A MIX OF PLATFORMS
This just isn’t a follow confined to bigger or cash-strapped international locations. Almost each navy has in its stock a mixture of new and older platforms, some on the verge of retirement and alternative.
Indeed, Singapore too isn’t any stranger to this follow. The Challenger-class submarines operated by the Republic of Singapore Navy’s had been acquired from Sweden, refurbished and upgraded for function.
The 4 had been already 30 years outdated when acquired by the RSN within the late Nineteen Nineties, two of that are nonetheless in service.
Even the RSAF’s fleet of F-16 fighter jets, at the moment being upgraded to maintain related, will solely be retired from the 2030s, which is able to imply the oldest jet can be round 35 years outdated at that time.
Part of this technique generally entails buying second-hand defence platforms. Beyond the low preliminary acquisition prices, used defence gear comes with person historical past, so a purchaser is much less prone to be shocked by unknown quirks and points with working the acquired system in the event that they accomplished due diligence with the previous operator.
They would know the failure price of particular person elements or subsystems based mostly on the previous operator’s historical past of maintenance, and get a clearer concept of what spares should be stocked up on and what areas to look out for when finishing up maintenance.
Buying second-hand gear provides a rustic a “ready to go” functionality, such that pressing necessities might be shortly met versus having to attend for a brand new fighter jet, tank or warship to be designed and constructed, which may take years.
HIGHER MAINTENANCE COSTS AS PLATFORMS AGE
The prices of working and sustaining platforms will naturally creep up as they age. For these causes, such gear should be diligently maintained. Serviceability may endure in any other case, imposing additional, further prices on militaries.
This dialogue over maintenance is related the place KRI Nanggala, a Cakra-class Type 209 submarine, was launched some 40 years in the past after the Indonesians bought it first-hand from Germany.
Indonesian media shops have reported that the submarine had missed a scheduled maintenance interval in 2020 which has been blamed by some quarters on the COVID-19 pandemic.
While it’s nonetheless not clear that the missed maintenance cycle is related to the sinking, the investigation into this occasion will little question be taking a look at this angle after investigators have mentioned they are going to study the impression of age on the submarine.
ROBUST PROGRAMME NEEDED
One of the primary challenges for militaries relating to working older gear is to maintain these methods going whereas guaranteeing that they continue to be fit-for-purpose within the face of obsolescence. As gear ages, a strong and well timed maintenance programme will change into extra vital, together with using preventive maintenance to catch potential points earlier than they occur.
This will contain extra intensive inspections carried out extra often, significantly for indicators of corrosion or metallic fatigue, in live performance with information gleaned from the producer’s or different operators’ experiences with comparable methods the place attainable.
Modern instruments for gear sustainment ought to be explored to see in the event that they can be utilized to maintain the serviceability of older methods at sufficiently excessive ranges.
These embrace using data-driven performance-based logistics fashions, which can lead to elevated serviceability charges, maintenance efficiencies and decrease prices all through the platform’s life cycle.
The Royal Australian Air Force (RAAF), for instance, has contracted Airbus Australia to take care of its fleet of Lockheed-Martin C-130J Hercules transport plane below a performance-based logistics assist contract since 2009.
Then Australian Defence Minister Christopher Pyne estimated that the contract extension signed in 2018 would save A$10 million (US$7.8 million) between 2019 and 2024
The RAAF, for its half, has reported that this sustainment mannequin has improved the provision of the 12-aircraft fleet, that are simply over 20 years outdated, by one further plane on common over an 18 month interval.
With this, the Australians can perform extra missions with the plane, to move personnel, provides and gear to assist Australian navy operations abroad, coaching, and humanitarian aid missions to the South Pacific.
Upgrade programmes primarily to make sure platforms stay related may also enhance the serviceability of older gear, with the alternative of particular elements that break down much less typically.
Another good instance is Singapore’s improve to its fleet of 70 second-hand A-4 Skyhawk fighter-bombers within the Nineteen Nineties. The outdated and more and more unreliable engines of the plane, most of which had taken half within the air battle over Vietnam within the Sixties whereas serving with the US Navy and Marine Corps, had been changed with a contemporary and extra highly effective substitute.
The transfer not solely considerably improved the efficiency of the jet, but in addition tackled straight a security concern because it successfully ended a spate of RSAF Skyhawk crashes within the mid-Nineteen Eighties led to by engine failures.
More broadly, the upgraded jets may proceed to serve the RSAF till the final plane had been retired in 2012, roughly 50 years after they rolled off the manufacturing unit flooring.
FOCUS ON SERVICEABILITY RATHER THAN AGE OF PLATFORMS
It is fiscally liable for militaries have to proceed working older gear so long as it’s operationally viable to take action. They should ought to extract as a lot worth as attainable out of high-priced defence gear and never take fiscal prudence flippantly.
However, to take action requires a strong programme to make sure serviceability, security, efficacy and value-for-money.
If something, this KRI Nanggala tragedy may spotlight how a lot the Indonesian Navy must dedicate extra funding and a spotlight to maintenance. This is the unglamorous facet of nationwide defence in comparison with shiny new gear, however is one space that can’t be uncared for.
