Opportunity Summary:

The Interrogative Anti Submarine Warfare (IASW) opportunity is a DARPA Strategic Technology Office research and development solicitation focused on radically shortening the Navy timeline from initial long-range submarine detection to engagement. In current tactical anti-submarine warfare (ASW), wide-area active sonar or other search sensors can generate an alert and a rough localization, but the next step almost always requires sending a manned platform to the suspected contact location to re-acquire and confirm the target. For surface ships, that typically means launching a helicopter to validate and, if appropriate, engage. For maritime patrol aircraft, it means the aircraft must interrupt its broad-area search pattern, descend, and devote time and payload to localization and prosecution. This sequential, manned validation step makes the force highly sensitive to false alarms, limits the number of contacts that can be handled at once, and slows the overall detect-to-engage chain.

IASW is looking for technology and system concepts that enable rapid, near-simultaneous interrogation of multiple long-range alerts without relying on the mission time, risk, and operational costs of manned aircraft. The central idea is to move from “one alert, one manned sortie” toward a model where a ship (and ideally other platforms) can quickly place or deliver multiple “proximity” sensors close enough to the uncertain target position to generate engagement-quality localization and high-confidence classification. If these sensors can be delivered quickly after an alert, the target’s movement and the time-late uncertainty are smaller, which increases the likelihood that sensors can be emplaced near the submarine and capture richer acoustic or other signatures. Those richer signatures, in turn, are intended to support more automated and reliable classification, reducing operator workload and decreasing the operational penalty associated with false alerts. DARPA also notes that successful approaches may have broader utility beyond shipboard ASW, potentially extending to maritime patrol aircraft concepts, persistent surveillance architectures, and future long-range detection and tracking systems.

Proposers are encouraged to structure solutions around three tightly coupled technical pillars. First is delivery: a method to rapidly place sensors so that multiple cued positions can be interrogated close to simultaneously rather than one-by-one. Second is sensing: proximity sensors must provide highly reliable detection and classification performance, implying robust signal collection and processing approaches suitable for real-world conditions and for discriminating submarines from clutter or benign contacts. Third is communication: the system must be able to extract and relay messages robustly from multiple long-range sensor locations, which DARPA flags as particularly challenging. Taken together, the envisioned end state is a concept of operations that preserves wide-area search while quickly “checking” multiple alerts in parallel, producing data good enough for confident decisions and potentially for future standoff engagement options.

From an administrative standpoint, this is published as DARPA BAA 09-24 under CFDA 12.910 (Research and Technology Development), categorized as discretionary science and technology R&D. The solicitation allows multiple funding instrument types (including grant and other procurement contract), has no cost-sharing or matching requirement, and is listed as open to unrestricted applicants, subject to any eligibility clarifications within the full announcement. Award floor and ceiling are not specified (both shown as 0), which typically indicates awards will be determined based on proposal merit, scope, and available funding rather than a pre-set range.

Security and facilities requirements are an explicit part of eligibility for execution. Performers must already have, before an award begins, approved personnel and facilities capable of conducting the proposed research at the required classification level, with at least SECRET as the minimum. This matters because many technical details, operational concepts, and test data in ASW-related work can involve classified information, and DARPA is making clear that a team cannot plan to “stand up” the needed cleared environment after selection.

Key dates and amendments included an Extension via Amendment 1: the proposal due date was changed from May 20, 2009 to June 2, 2009 (updated in multiple sections of the BAA). The opportunity was posted March 12, 2009, and the listing shows an original and current closing date of March 10, 2010, with an archive date of April 9, 2010, reflecting how the announcement was managed on government posting systems. The full BAA package (referenced as a Word document attachment) contains the detailed area of interest, submission instructions, required formats, and contractual and administrative terms. Questions (administrative, technical, or contractual) were directed to the program email address BAA09-24@darpa.mil, with requests required to include a point of contact name, address, and phone number.

Frequently Asked Questions (FAQ) - Interrogative Anti Submarine Warfare (IASW) (DARPA BAA 09-24)

What is the IASW opportunity?

Interrogative Anti Submarine Warfare (IASW) is a DARPA Strategic Technology Office research and development solicitation aimed at radically shortening the U.S. Navy timeline from initial long-range submarine detection to engagement.

What problem is IASW trying to solve in current ASW operations?

In current tactical anti-submarine warfare (ASW), long-range sensors (such as wide-area active sonar) may generate an alert and rough localization, but confirmation typically requires a manned platform to re-acquire and validate the contact. This sequential validation step slows the detect-to-engage chain, makes operations sensitive to false alarms, and limits how many contacts can be handled at the same time.

Why are manned platforms a bottleneck in the current detect-to-engage chain?

For surface ships, a helicopter is often launched to validate and possibly engage. For maritime patrol aircraft, the aircraft often must interrupt broad-area search, descend, and devote time and payload to localizing and prosecuting a contact. This consumes mission time and increases the operational cost of handling false alerts.

What is DARPA’s central concept for IASW?

IASW seeks technology and system concepts that allow rapid, near-simultaneous interrogation of multiple long-range alerts by quickly placing or delivering multiple proximity sensors close enough to uncertain target locations to produce engagement-quality localization and high-confidence classification, without relying on manned aircraft for validation.

What does “one alert, one manned sortie” mean, and what does IASW want instead?

“One alert, one manned sortie” describes the typical process where each long-range alert triggers a manned flight to confirm it. IASW aims to shift toward a model where a ship (and ideally other platforms) can rapidly deploy multiple sensors to check multiple alerts in parallel.

What are “proximity sensors” in the context of IASW?

In IASW, proximity sensors are sensors intended to be placed close enough to the suspected submarine location to collect richer acoustic or other signatures, enabling engagement-quality localization and high-confidence classification.

Why does IASW emphasize rapid delivery of sensors after an alert?

If sensors can be delivered quickly after an alert, the submarine has less time to move, reducing time-late uncertainty. This increases the likelihood that sensors can be placed near the submarine and collect higher-value signatures useful for reliable classification.

How does IASW expect to reduce the impact of false alarms?

By enabling richer signature collection and more automated, reliable classification near the alerted location, IASW intends to reduce operator workload and reduce the operational penalty associated with false alerts.

What types of technical approaches is DARPA encouraging for IASW?

DARPA encourages proposers to structure solutions around three tightly coupled technical pillars: delivery, sensing, and communication.

What is the “delivery” pillar?

Delivery refers to methods to rapidly place sensors so that multiple cued positions can be interrogated close to simultaneously rather than one-by-one.

What is the “sensing” pillar?

Sensing refers to proximity sensors achieving highly reliable detection and classification performance, including robust signal collection and processing suitable for real-world conditions and capable of discriminating submarines from clutter or benign contacts.

What is the “communication” pillar, and why is it emphasized?

Communication refers to the system’s ability to extract and relay messages robustly from multiple long-range sensor locations. DARPA specifically flags this as particularly challenging.

What is the intended operational end state for IASW concepts?

The envisioned end state is a concept of operations that preserves wide-area search while quickly checking multiple alerts in parallel, producing data sufficient for confident decisions and potentially supporting future standoff engagement options.

Is IASW limited to shipboard anti-submarine warfare?

Successful approaches may have broader utility beyond shipboard ASW, including potential extension to maritime patrol aircraft concepts, persistent surveillance architectures, and future long-range detection and tracking systems.
