Defence programmes frequently operate across multiple decades, nations, suppliers and support partners. This means planning, communications and placing orders are particularly complex and potentially long-winded. ObsLogic helps organisations to develop a more strategic approach to sustainment planning by greatly improving how quick and easy it is to identify and plan for:

• At-risk components
• Supplier status
• Last-time-buy requirements
• Consumption forecasting
• Stock implications
• Mitigation options
• Cross-platform impact

ObsLogic can help support engineering and airworthiness activities by improving visibility, traceability and management of obsolescence-related risks and decisions.

In complex defence aviation environments, obsolescence issues can have direct implications for airworthiness, safety, maintenance planning and operational availability. Components becoming unavailable, unsupported or increasingly difficult to source may introduce engineering, certification and sustainment challenges that need to be understood and managed in a controlled and auditable manner.

ObsLogic helps organisations develop a more structured approach to managing these risks. 

By providing a centralised environment for tracking obsolescence notifications, engineering assessments, mitigation activity and decision history, ObsLogic supports greater visibility across the lifecycle of an issue. This can help engineering and support teams:

• identify potential airworthiness impacts earlier 
• improve traceability of technical and commercial decisions 
• maintain clearer evidence and audit trails 
• coordinate activity across engineering, supply chain and support functions 
• prioritise risks based on operational and engineering impact 
• support more informed sustainment and assurance activity 

The application can also help reduce reliance on fragmented spreadsheets, emails and disconnected tracking processes, improving consistency and visibility across programmes and fleets.

For organisations operating within regulated defence engineering environments, this more structured and transparent approach can help support stronger governance, improved risk management and more effective through-life airworthiness planning.

Obsolescence management software helps organisations to identify, track and manage components, materials and systems that are becoming unavailable or unsupported.

Military aircraft often remain in service for decades, while suppliers and technologies change much more rapidly. Effective obsolescence management helps maintain aircraft availability, safety and supportability.

A last-time-buy (LTB) decision occurs when an organisation purchases components before a supplier permanently stops production or support. In complex military equipment environments, these decisions can be particularly challenging because platforms such as military aircraft, naval systems and defence electronics often remain operational for decades after original manufacturers have moved on from the underlying technologies or materials.

When a supplier issues an obsolescence notification or withdraws support for a component, engineering and support teams may need to determine:

• how many parts remain available 
• how quickly those parts are likely to be consumed 
• the expected out-of-service date of the platform 
• whether alternative components or redesign options exist 
• the operational and airworthiness implications of future shortages 
• the financial risk of over- or under-purchasing stock 

ObsLogic helps bring structure, visibility and traceability to this process. 

Effective last-time-buy planning relies on accurate forecasting, engineering insight and strong visibility across supply chain, maintenance and operational data.

Without a structured approach, organisations risk increased downtime, rising sustainment costs, reduced fleet availability and pressure on operational capability later in the platform lifecycle.

 and controlled ownership that are difficult to achieve using disconnected manual methods.

Integration capability will depend on organisational requirements, existing digital environments and applicable security or regulatory constraints. tlmNexus can discuss potential integration approaches as part of project scoping and technical assessment activity.

In many defence engineering and support environments, obsolescence management information already exists across multiple systems, teams and data sources. Depending on operational requirements, organisations may wish to align obsolescence activity with areas such as:

• engineering issue management 
• supply chain and inventory systems 
• maintenance and support systems 
• technical documentation 
• reporting and analytics environments 
• airworthiness and assurance processes 

The appropriate level of integration will vary between programmes and organisations, particularly where legacy systems, security considerations or platform-specific processes are involved.

ObsLogic is intended to support a more connected and visible approach to obsolescence management, while recognising that implementation and integration requirements may differ significantly across defence environments.
